OBJECTIVE: Obesity is a global health problem that increases the risk of coronary artery disease (CAD). However in studies, it has been observed that when the disease develops, obese patients have a more favorable prognosis than leaner patients. This is called the "obesity paradox." This study aims to evaluate the effect of obesity assessed with body fat percentage (BFP) and relative fat mass (RFM) besides body mass index (BMI) on infarct size (IS) estimated from peak creatine kinase-MB (CKMB) levels in patients with non-ST-segment elevation myocardial infarction (NSTEMI). METHODS: Patients with a diagnosis of NSTEMI who underwent coronary angiography between January 2017 and January 2022 were retrospectively evaluated. Patients without available anthropometric data to calculate BMI, BFP, and RFM and serial CK-MB measurements were excluded from the study. BMI was calculated using weight(kg)/(height[m])2 formula. Patients were dichotomized as obese (BMI=30 kg/m2) and non-obese (BMI<30 kg/m2) to compare baseline characteristics. BFP and RFM were calculated from anthropometric data. Linear regression analysis was performed to define predictors of IS. RESULTS: Final study population consisted of 748 NSTEMI patients (mean age was 59.3±11.2 years, 76.3% were men, 36.1% of the patients were obese). Obese patients were more likely to be female, hypertensive, and diabetic. Smoking was less frequently observed in obese patients. Peak CK-MB levels were similar among groups. Obese patients had higher in-hospital left ventricular ejection fraction, and less severe CAD was observed in coronary angiographies of these patients. Multivariable regression analysis identified diabetes mellitus, systolic blood pressure, white blood cell count, hemoglobin, and BFP (β'=-4.8, 95% CI=-8.7; -0.3, p=0.03) as independent predictors of IS. CONCLUSION: Higher BFP is associated with smaller IS in NSTEMI patients. These findings support the obesity paradox in this patient group, but further, randomized controlled studies are required.

Percutaneous structural interventions are being performed at increased numbers and rare findings or complications occur more frequently. Lipomatous hypertrophy of the interatrial septum (LHIS) is a relatively uncommon finding on transthoracic echocardiogram (TTE). The major challenge is the difficulty in performing transseptal puncture. We aimed to report the difficulties that were experienced during the left atrial appendage (LAA) closure in a case with an extreme form of LHIS. [ABSTRACT FROM AUTHOR]

Corrected thrombolysis in myocardial infarction frame count (cTFC) is an objective, simple, and reproducible method to assess coronary blood flow which is a surrogate for cardiovascular outcomes. It is important to learn which factors are associated with cTFC. The goal of this study was to determine predictive models for epicardial blood flow assessed by cTFC and develop a diagnostic predictive model that indicates the individualized assessment of epicardial blood flow prior to primary percutaneous coronary intervention. This is a retrospective study including 3205 patients with ST-segment elevation myocardial infarction who underwent pPCI. The primary outcome was cTFC. Multivariable linear regression analysis was performed. Subsequently, a nomogram was developed to predict cTFC according to the candidate predictors. Median age was 58; the number of male patients was 2381 (74.3%). Median value of cTFC was 22 and interquartile range (IQR): 16.5–28.0). Age, diabetes mellitus (DM), total ischemic time, systolic blood pressure (SBP), heart rate (HR), and history of statin use remained in both full and reduced models. Our model may potentially allow clinicians to identify patients at high risk for impaired epicardial perfusion. [ABSTRACT FROM AUTHOR]

In this study, we aimed to evaluate the predictive value of admission C-reactive protein/albumin ratio (CAR) for acute kidney injury (AKI) in cases with moderate to severe chronic kidney disease (CKD) not on dialysis who presented with non-ST-segment elevation myocardial infarction (NSTEMI) and underwent coronary angiography (CAG). This cross-sectional and observational study included 420 NSTEMI patients. The study population was categorized based on the CAR tertiles as groups T1, T2, and T3. The primary outcome of the study was AKI development; 92 (21.9%) cases developed AKI. The frequency of AKI was significantly higher in the T3 group compared with the T2 and T1 groups (34% vs 17% vs 14%, P <.001). Age, estimated glomerular filtration rate, contrast media volume, and CAR (odds ratio: 1.36; 95% CI: 1.17-1.57; P <.01) were significant predictors of AKI. In a receiver operating characteristic curve analysis, CAR levels >0.20 predicted AKI development with a sensitivity of 74% and a specificity of 45%. We observed that the CAR may be a promising inflammatory parameter for AKI in NSTEMI patients with moderate to severe CKD after CAG. [ABSTRACT FROM AUTHOR]
