Aim: The number of diagnostic coronary angiography is increasing. Although previously thought that non-obstructive coronary artery disease (CAD) does not cause an increase in mortality risk, there is recently evidence that it increases mortality. In this study, we aimed to determine the mortality rates and possible predictors of all-cause death in long-term follow-up of patients who underwent coronary angiography (CAG) due to stable angina and whose SYNTAX score was zero including normal coronary arteries, minimal CAD or non-obstructive CAD, coronary slow flow, coronary artery aneurysms and ectasia. Materials and Methods: This study included 1489 patients who underwent CAG due to stable angina pectoris. In-hospital and post-discharge follow-up data were obtained. Patients' CAG images were evaluated and SYNTAX scores were calculated using the website calculator. Results: Among the 1489 patients, 64 (4.3%) all-cause deaths were observed during the 19 ± 1.1 months of follow up period. Although, no significant difference was observed between the 2 groups in terms of the presence of plaque in coronary arteries with a vessel diameter of ≤ 1.5 mm, the rate of patients with plaque in coronary arteries with a diameter of > 1.5 mm was significantly higher in the group of patients who died compared to the patients living (48 (75%) vs 842 (% 59.1), p = 0.011). The cumulative survival curve of the patients was obtained and in patients with coronary plaque in any of the coronary arteries with a vessel diameter of > 1.5 mm was significantly associated with worse survival. Conclusion: There was increase in all-cause mortality in patients who underwent CAG due to stable angina and who have at least one non-obstructive lesion in the coronary arteries > 1.5 mm. Therefore, appropriate risk classification, life style changes and appropriate medical follow-up may be important in these patients. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to evaluate the predictive role of the Geriatric Nutrition Risk Index in long-term mortality of very elderly patients with ST-segment elevation myocardial infarction and to compare it with the other known objective nutritional indices, namely the Prognostic Nutritional Index and Controlling Nutritional Status. Materials and Methods: A total of 212 eligible patients, aged 80 years or older, who were hospitalized with a diagnosis of ST-segment elevation myocardial infarction and underwent primary percutaneous coronary intervention were included in the study. Baseline patient characteristics, echocardiographic assessments, laboratory findings, and nutritional indices were assessed. Results: During the median follow-up period of 34 months, 60 (28.3%) allcause mortalities were identified, and event-free cumulative rates were 46.3%, 81.4%, and 90.1% for Geriatric Nutrition Risk Index <100.5, 100.5-112.6, and >112.6, respectively (log-rank test, p < 0.0001). Receiver operating characteristic curve comparison analysis revealed that the Geriatric Nutrition Risk Index was a better predictor than the Controlling Nutritional Status, Prognostic Nutritional Index, Body Mass Index, and serum albumin (p < 0.001 for each pairwise comparison of Receiver operating characteristic curves). Conclusion: It is important to evaluate malnutrition that is known to be associated with mortality in very elderly patients with ST-segment elevation myocardial infarction, who are more fragile than young people, and Geriatric Nutrition Risk Index -a simple and easy-to-calculate index-can be a guide in this regard.

Objective: Acute kidney injury (AKI), which is prevalent in ST-segment elevated myocardial infarction (STEMI) patients who have undergone primary percutaneous coronary intervention (PCI), is associated with poor cardiovascular outcomes. As high pulse pressure (PP) is associated with adverse cardiovascular events, the present study's aim was to evaluate the relationship between fractional PP (PPf) and AKI in patients with STEMI who underwent primary PCI.Subjects and Methods: All laboratory findings as well as echocardiographic and angiographic data of 1,170 consecutive STEMI patients were retrospectively screened. PPf was calculated from the pressures invasively measured after sheath insertion and before performing coronary angiography.Results: From 1,170 eligible STEMI patients (mean age 56 years, 18.2% female), AKI developed in 143 (12.2%) patients. The PPf and pulsatility index were significantly higher in patients with AKI than those without (0.53 ± 0.10 vs. 0.61 ± 0.10, p < 0.001, and 0.80 ± 0.03 vs. 0.82 ± 0.03, p < 0.001, respectively). PPf was also found to be associated with AKI in univariable (OR 2.183, 95% CI 1.823-2.614, p< 0.001) and multivariable (OR 1.874, 95% CI 1.513-2.322, p < 0.001) analysis. In-hospital mortality was higher in patients with AKI than those without.Conclusion: Invasively measured PPf, which can be easily measured and has no additional cost in STEMI patients undergoing coronary intervention, is an independent predictor of AKI. In addition, PPf is superior to other blood pressure values and derivatives in AKI prediction. [ABSTRACT FROM AUTHOR]

Left ventricular diastolic dysfunction (LVDD) is commonly seen in hypertensive patients, and it is associated with increased morbidity and mortality. Hence, the detection of LVDD with a simple, inexpensive, and easy-to-obtain method can contribute to improving patient prognosis. Therefore, we aimed to evaluate whether there was any association between the electrocardiographic P wave peak time (PWPT) and invasively measured left ventricular end-diastolic pressure (LVEDP) in hypertensive patients who had undergone coronary angiography following preliminary diagnosis of coronary artery disease. A total of 78 patients were included in this cross-sectional study. The PWPT was defined as the time from the beginning of the P wave to its peak, and it was calculated from the leads DII and VI . In all patients, LVEDP was measured in steady state. The PWPT in lead DII was significantly longer in patients with high LVEDP; however, there was no significant difference between groups in terms of PWPT in the lead VI . In multivariable analysis, PWPT in lead DII was found to be independent predictor of increased LVEDP (OR: 1.257, 95% CI: 1.094-1.445; P = 0.001). In receiver operating characteristic curve analysis, the optimal cut-off value of PWPT in the lead DII for prediction of elevated LVEDP was 64.8 ms, with a sensitivity of 68.7% and a specificity of 91.3% (area under curve: 0.882, 95% CI: 0.789-0.944, P < 0.001). In conclusion, this study result suggested that prolonged PWPT in the lead DII may be an independent predictor of increased LVEDP among hypertensive patients. [ABSTRACT FROM AUTHOR]

Background/aim: The number of patients with heart transplantation has dramatically increased in the last decade. Considerable studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. We analyzed the dispersion of myocardial repolarization using electrocardiographic Tp-e interval and Tp-e/QTc ratio in patients with heart transplantation. Materials and methods: This observational study included 38 patients (12 female and 26 male) with heart transplantation and 38 wellmatched controls. From electrocardiograms, Tp-e interval and Tp-e/QTc ratio were calculated and compared between the 2 groups. Results: Noninvasive arrhythmia indicators including Tp-e interval (84.63 ± 14.17 ms vs 71.82 ± 7.47 ms, P < 0.001), Tp-e/QTc ratio (0.19 ± 0.04 vs 0.16 ± 0.02, P < 0.001) and QTc interval except QT interval were significantly higher in transplanted hearts compared to normal hearts. Conclusion: Patients with heart transplantation have increased myocardial dispersion of repolarization. [ABSTRACT FROM AUTHOR]

Background: Rheumatic heart disease (RHD) is a serious health concern in developing countries. Rheumatic mitral stenosis (RMS) is the most long-term sequel in RHD. The neutrophil to lymphocyte ratio (NLR) is a novel marker, and a higher NLR has been associated with poor clinical outcomes in various cardiovascular disorders. We evaluated the availability of NLR to predict severity of mitral stenosis (MS) in patients with RHD. Methods: We analyzed 300 consecutive patients with RMS. The patients were divided into tertiles according to NLR: 0.85< NLR ⩽1.85 (n=100, tertile 1), 1.86⩽ NLR ⩽2.46 (n=100, tertile 2), and 2.47⩽ NLR ⩽7.08 (n=100, tertile 3). Patients with RMS were divided into three groups based on the degree of MS as mild, moderate, and severe MS. After the initial evaluation, 187 patients with moderate-to-severe RMS (Group 1) and 113 patients with mild RMS (Group 2) were reassessed. Results: The patients with severe RMS had significantly elevated NLR, mean platelet volume, and pulmonary artery systolic pressure values compared to patients with moderate and mild MS (P<0.001, P<0.001, P<0.001 respectively). Multivariate binary logistic regression analysis revealed that high levels of NLR was an independent predictor of severe RMS (odds ratio =0.68, P=0.008). Moderate-to-severe RMS incidence was significantly higher among patients in the tertile 3 (odds ratio =2.8, P=0.001). Conclusion: NLR is a new inflammatory marker and a simple, rapid, and easily accessible prognostic parameter that can be associated with severity of RMS in patients with RHD. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusion Mitral annular flutter (MAF) is the most common left atrial macro‐reentrant arrhythmia following catheter ablation of atrial fibrillation (AF). The best ablation approach for this arrhythmia remains unclear.This single‐center, retrospective study sought to compare the acute and long‐term outcomes of patients with MAF treated with an anterior mitral line (AML) versus a mitral isthmus line (MIL). Acute ablation success, complication rates, and long‐term arrhythmia recurrence were compared between the two groups.Between 2015 and 2021, a total of 81 patients underwent ablation of MAF (58 with an AML and 23 with a MIL). Acute procedural success defined as bidirectional block was achieved in 88% of the AML and 91% of the MIL patients respectively (p = 1.0). One year freedom from atrial arrhythmias was 49.5% versus 77.5% and at 4 years was 24% versus 59.6% for AML versus MIL, respectively (hazard ratio [HR]: 0.38, confidence interval [CI]: 0.17–0.82, p = .009). Fewer patients in the MIL group had recurrent atrial flutter when compared to the AML group (HR: 0.32, CI: 0.12–0.83, p = .009). The incidence of recurrent AF, on the other side, was not different between both groups (21.7% vs. 18.9%; p = .76). There were no serious adverse events in either group.In this retrospective study of patients with MAF, a MIL compared to AML was associated with a long‐term reduction in recurrent atrial arrhythmias driven by a reduction in macroreentrant atrial flutters.

Background: Different arterial segments throughout the vascular system develop similar grades of atherosclerosis concomitantly. Urethral ischemia has been proposed as a cause of urethral stricture. Therefore, we aimed to investigate the relationship between coronary artery disease severity using a SYNTAX score and urethral stricture occurrence after urethral catheterization in patients with non--ST-segment-elevation acute coronary syndrome (ACS). Methods: This retrospective study consisted of 306 men with urethral catheters that were diagnosed with ACS and underwent coronary angiography between January 2016 and January 2018 in Kars Kafkas University and Osmaniye Government Hospital, Turkey. Hospital records were reviewed to collect the follow-up data of the patients regarding the occurrence of urethral stricture after urethral catheterization. The study population was divided into 2 groups according to urethral stricture development, and both groups were compared statistically. Results: SYNTAX scores were significantly higher in patients with urethral stricture than in those without urethral stricture (14.86±7.11 vs. 29.25±9.79; P<0.001). The SYNTAX score (OR=1.27; 95% CI: 1.16-1.39; P<0.001), diabetes, and serum albumin were found to be the independent predictors of urethral stricture. The receiver operating characteristic curve analysis showed that the cutoff value of the SYNTAX score for urethral stricture prediction was greater than 22.5, with 76.7% sensitivity and 85.1% specificity (AUC=0.88, 95% CI: 0.84-0.91; P<0.001). Conclusion: Coronary artery disease severity graded according to the SYNTAX score is an independent predictor of urethral stricture occurrence in ACS patients with a urethral catheter inserted.

Objective: An increased left atrial volume index (LAVI) is related to increased mortality in hemodialysis patients. In the present study, we evaluated the association between the LAVI and the P wave peak time (PWPT), a newly introduced electrocardiographic parameter, in hemodialysis patients.Methods: The study population was made up of 79 hemodialysis patients with a mean age of 53 ± 18 years (55.7% were males). These patients were divided into a normal LAVI (≤28 mL/m2) group (n = 45) and an increased LAVI (>28 mL/m2) group (n = 34). The demographic, clinical, laboratory, echocardiographic, and electrocardiographic variables of the groups were compared.Results: The P wave terminal force from lead V1, P wave dispersion and PWPTs obtained from leads V1 and D2 (PWPTD2) were significantly higher in the patients with increased LAVIs. In multivariable analysis, only the PWPTD2was an independent predictor of an increased LAVI (odds ratio = 1.117, 95% CI = 1.052-1.185, p < 0.001). The receiver-operating characteristic curve analysis showed that the best PWPTD2 cutoff value for predicting an increased LAVI was 60 ms, with a sensitivity of 76.5% and a specificity of 66.7% (area under the curve = 0.736, 95% CI = 0.625-0.829, p < 0.001).Conclusion: This study showed that a prolonged PWPTD2 was independently associated with an increased LAVI in hemodialysis patients. Therefore, measuring the PWPTD2 duration on an electrocardiogram may help define high-risk hemodialysis patients with increased LAVIs. [ABSTRACT FROM AUTHOR]

Ramadan interferes with circadian rhythms mainly by disturbing the routine patterns of feeding and smoking. The objective of this study was to investigate the circadian pattern of ST elevation acute myocardial infarction (STEMI) during the month of Ramadan. We studied consecutive STEMI patients 1 month before and after Ramadan (non-Ramadan group-NRG) and during Ramadan (Ramadan group-RG). The RG group was also divided into two groups, based on whether they chose to fast: fasting (FG) and non-fasting group (NFG). The time of STEMI onset was compared. A total of 742 consecutive STEMI patients were classified into 4 groups by 6 h intervals according to time-of-day at symptom onset. No consistent circadian variation in the onset of STEMI was observed both between the RG (P =.938) and NRG (P =.766) or between the FG (P =.232) and NFG (P =.523). When analyzed for subgroups of the study sample, neither smoking nor diabetes showed circadian rhythm. There was a trend towards a delay from symptom onset to hospital presentation, particularly at evening hours in the RG compared with the control group. In conclusion, there was no significant difference in STEMI onset time, but the time from symptom onset to hospital admission was significantly delayed during Ramadan. [ABSTRACT FROM AUTHOR]

Blunt chest traumas mostly occur due to car accidents and can cause many cardiac complications such as septal rupture, free-wall rupture, coronary artery dissection or thrombosis, heart failure, arrhythmias, and chordae and papillary muscle rupture. One of the most serious complication is tricuspid regurgitation (TR), which can be simply diagnosed by physical examination and confirmed by echocardiography. We describe a 48-year-old female patient, diagnosed with severe TR 13 years after a blunt chest trauma due to a car accident. TR was diagnosed with transthoracic echocardiography and three dimensional transthoracic echocardiography had defined the exact pathology of the tricuspid valve. The patient underwent successful surgery with bioprosthetic valve implantation and was discharged at 6th postoperative day without any complication. The patient had no problem according to the follow-up one month and six months after operation. [ABSTRACT FROM AUTHOR]

Purpose: The aim of our study was to determine whether the RS time measured on an electrocardiogram is associated with the severity of chronic obstructive pulmonary disease (COPD). Materials and Methods: The study population was made up of 100 COPD patients with a mean age of 63 ± 10 years (86% were males). These patients were divided into the mild and moderate COPD (GOLD 1–2) group (n = 45) and the severe and very severe COPD (GOLD 3–4) group (n = 55) according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages. These groups were compared with each other. Results: Heart rate, P wave axis, QRS axis, RS time, and incidence of right bundle branch block were significantly higher in patients with severe and very severe COPD. In the multivariable analysis, heart rate, P wave axis, and RS time (odds ratio = 1.081) were the independent predictors of severe and very severe COPD. The receiver operating characteristic curve analysis showed that the best RS time cutoff value for the prediction of severe and very severe COPD was 60 ms, with a sensitivity of 69.1% and a specificity of 66.7%. Conclusion: RS time simply measured on an electrocardiogram may be a useful screening test for the quick estimation of patients with severe and very severe COPD. [ABSTRACT FROM AUTHOR]

Introduction and objectives: The aim of this study was to investigate the association of serum albumin (SA) level with long‐term prognosis in patients with acute pulmonary embolism (PE). Materials and methods: We retrospectively enrolled 269 patients with acute PE. The SA level was obtained within 12‐24 hours following admission. The primary endpoints were the incidence of short‐ and long‐term mortality in acute PE patients. The mean duration of the study follow‐up was 21 ± 19 months. Results: During the follow‐up period, short‐ and long‐term mortality rates were higher in patients who had low SA level compared to those who did not have. In multivariate Cox regression analysis, the SA level was found to be independently associated with long‐term mortality (HR: 0.47, 95%CI: 0.28‐0.78, P = 0.004). In receiver operating characteristics analysis, the SA level of ≤3.17 predicted long‐term mortality with a sensitivity of 77.5% and a specificity of 79.5% (area under the curve 0.82, 95%CI: 0.76‐0.87, P < 0.001). In addition, when the SA plus simplified pulmonary embolism severity index (sPESI) risk score compared to the sPESI risk score alone, it produced a net reclassification improvement of 0.22 with P < 0.001, that is a 22% improved classification. Conclusion: To the best of our knowledge, this is the first study to demonstrate that the low SA level is a strong and independent predictor for long‐term mortality in patients with acute PE.

Contrast-induced nephropathy (CIN) is a prevalent and serious complication after primary percutaneous coronary intervention (pPCI). Although the association between serum osmolarity and chronic kidney disease is well established, its relation to CIN in patients with ST-segment elevation myocardial infarction (STEMI) undergoing pPCI needs to be elucidated. We evaluated the predictive value of serum osmolarity for CIN development in patients with STEMI (n = 768) undergoing pPCI. Serum osmolarity on admission was calculated. The study population was divided into 2 groups according to CIN development, and both groups were compared according to clinical, laboratory, and demographic features, including the serum osmolarity. Serum osmolarity was significantly higher in patients with CIN than in those without CIN (278 [8] vs 284 [9]; P =.024). Serum osmolarity (odds ratio: 1.052; 95% confidence interval: 1.018-1.086; P =.002), hemoglobin, contrast media volume, creatinine on admission, basal SYNergy between PCI with TAXus and cardiac surgery II score, and left ventricular ejection fraction were found to be independent predictors of CIN. Serum osmolarity (given the simple calculation of this parameter on admission) can be useful to define patients with STEMI undergoing pPCI who are more likely to develop CIN. [ABSTRACT FROM AUTHOR]

The aim of this study is to investigate the impact of ticagrelor as compared to clopidogrel based dual antiplatelet therapy (DAPT) during post-discharge management on the incidence of left ventricular (LV) thrombus in patients with first acute anterior ST elevation myocardial infarction (STEMI). 641 patients who met the inclusion criteria were divided into two groups based on the receipt of either ticagrelor or clopidogrel based DAPT. Left ventricular thrombus was detected in 73 (11.4%) patients at the first month echocardiographic examination. Ticagrelor based DAPT was associated with significantly less incidence of LV thrombus when compared to clopidogrel [20 (7.4%) vs 53 (14.0%) OR: 0.50 (0.29–0.86)]. Penalized maximum likelihood estimation (PMLE) logistic regression analyses were performed to fourteen candidate variables for identifying the independent predictors of LV thrombus, ticagrelor (compared with clopidogrel) [OR: 0.53 (0.28–0.96), p = 0.039], body mass index (BMI) [OR: 0.58 (0.44–0.77), p < 0.001], KILLIP class (I vs II–IV) [OR: 0.35 (0.14–0.83), p = 0.017], age [OR: 1.22 (1.08–1.40), p < 0.001], poor postprocedural myocardial blush grade (MBG) [OR: 3.35 (1.32–8.15), p = 0.012] and LVEF predischarge [OR: 0.79 (0.72–0.86), p < 0.001] were found to be associated with LV thrombus. Our study demonstrated that the incidence of LV trombus was significantly lower with ticagrelor than clopidogrel-based DAPT during postdischarge treatment for anterior STEMI patients. • Left ventricular thrombus is a potential source of systemic embolization after STEMI. • Prophylactic treatment in addition to DAPT is not recommended after discharge. • Ticagrelor has faster and achieves more consistent P2Y12 inhibition than clopidogrel. • The incidence of left ventricular thrombus is lower with ticagrelor than clopidogrel.

• Considering the worse prognosis of elderly STEMI patients, an identifying the most suitable risk scoring system is crucial. • We observed that the Syntax Score (SS) II was an independent predictor of long-term mortality in octogenarians. • A ROC comparison showed that SSII was a better predictor of long-term mortality than SS, PAMI, TIMI, and GRACE risk scores. • The SSII may be a better predictor of mortality than other risk-scoring systems in octogenarians. The aim of this study was to evaluate the usefulness of the Syntax Score II (SSII) in predicting in-hospital and long-term mortality in octogenarians who presented with ST-segment elevation myocardial infarction (STEMI) and were treated with primary percutaneous coronary intervention (pPCI) in addition to compare SS II with other risk-scoring systems. We retrospectively enrolled 312 consecutive STEMI patients in the eighth decade of life or older who underwent pPCI. The octogenarians were divided into two groups according to their median SSII (low SSII ≤ 43.6 and high SSII > 43.6), and these groups were compared in terms of mortality. The performance of the SSII in predicting patients' outcomes was further compared with that of other well-known risk-scoring systems. In the study, the SSII was an independent predictor of long-term mortality (OR: 1.036 95% CI: 1.005–1.068; p = 0.024). Both in-hospital (20.8% vs. 1.2%; p < 0.001) and long-term mortality (45.0% vs. 11%; p < 0.001) were higher among the patients with a high SSII compared to those with a low SSII. An ROC curve comparison showed that SSII was a better predictor (AUC: 0.807; 95% CI: 0.750-0.863) of long-term mortality than SS, PAMI, TIMI, and GRACE risk scores but not CADILLAC. Based on the study findings, octogenarians with a high SSII had worse in-hospital and long-term survival. The SSII, which includes several clinical and anatomical parameters, may be a better predictor of mortality than other risk-scoring systems in octogenarians. [ABSTRACT FROM AUTHOR]

Abstract: Background: The ratio of serum C‐reactive protein (CRP) to albumin has been proven to be a more accurate indicator than albumin and CRP levels alone in determining the prognosis of patients with cancer and critical illness. The aim of this study was to determine whether the CRP/albumin ratio (CAR) can be linked to imperfect reperfusion that can worsen the prognosis of ST‐elevation myocardial infarction (STEMI) in patients treated with primary percutaneous coronary intervention (pPCI). Materials and methods: A total of 1217 consecutive STEMI patients who achieved epicardial vessel patency with pPCI were recruited to this study. Results: The study population was divided into 2 groups: reflow (n = 874) and no‐reflow (NR) (n = 343) groups. The white blood cell count (WBC), neutrophil‐to‐lymphocyte ratio (NLR) and CAR (0.03 [0.01‐0.04] vs 0.06 [0.03‐0.12] (P < .001) were significantly higher in the NR group than in the reflow group, and these factors were found to be independent predictors of NR development. The best cut‐off value of CAR predicting NR was 0.59 with a sensitivity of 54.7% and specificity of 86.7. The predictive power of CAR surpassed that of CRP, albumin, WBC count and NLR in the receiver operator curve (ROC) curve comparison. Conclusion: No‐reflow can be predicted by systemic inflammation markers including WBC count, NLR and CAR measured from the blood sample obtained on admission. CAR has a higher clinical value than CRP, albumin level, WBC count and NLR in NR prediction. [ABSTRACT FROM AUTHOR]

Background: Coronary heart disease the leading cause of mortality worldwide and regular physical activity is a comprehensive management strategy for these patients. We investigated the parameters that influence regular physical activity in patients with a history of coronary revascularization. Methods: We included outpatients who had a history of coronary revascularization at least 6 months prior to enrollment. A questionnaire was filled out with each patient to collect the data of engagement in regular physical activity, demographics, clinical characteristics, and dietary adherence. Results: We enrolled 202 consecutive outpatients (age 61.3±11.2 years, 73% males). The median duration after revascularization was 60 months. One hundred and 4 (51%) patients had previous percutaneous coronary intervention, 67 (33%) patients had coronary by-pass graft surgery, and 31 (15%) patients had both of the revascularization procedures. Of all, 46 (23%) patients were engaging in regular physical activity with a median of 2 days per week. Patients were classified into two subgroups according to their physical activity habits. There was no significant difference in age, comorbid conditions or revascularization type between subgroups. In the univariate regression analysis, absence of regular physical activity was associated with female gender, low education level, unemployment, low household income, implantation of bare metal stent (vs. drug eluted stent) and absence of regular follow-up visits. Stepwise multivariate regression analysis concluded that low education level (p=0.01, OR=3.26, 95%CI: 1.31 -8.11), and absence of regular follow-up visits (p=0.04, OR=2.95, 95%CI: 1.01-8.61) were independent predictors of non-adherence of regular physical activity in study subjects. Conclusion: Regular physical activity rates were lower in outpatients with a history of previous coronary revascularization. Education level and regular follow-up visits could influence physical activity adherence in these patients. [ABSTRACT FROM AUTHOR]
