Background: Early systolic lengthening is a echocardiographic strain parameter previously used to determine the lesion severity in patients with stable coronary artery disease. In the present study, we aimed to evaluate the relationship between early systolic lengthening and anatomic SYNTAX score in troponin (-) and (+) groups among patients with non-ST-elevation acute coronary syndrome (ACS). Methods: A total of 95 patients diagnosed with non-ST-elevation ACS were included in the prospective, non-randomized, single-center study. The patients were categorized into 2 groups as troponin (+) and troponin (-). The patients were evaluated in terms of echocardiographic, clinical, and angiographic parameters. Results: The baseline characteristics, including age (58 ± 13 vs. 60 ± 10 respectively, P = .340), a history of hypertension (67.1% vs. 64%, respectively, P = .479), diabetes (28.6% vs. 32%, respectively, P = .467), global longitudinal strain (-14.37 ± 5.11 vs. -16.42 ± 3.93, respectively, P = .095), left ventricular ejection fraction (58.71 ± 8.73 vs. 57.20 ± 8.70, respectively, P = .263), and E/e' (8.44 ± 2.13 vs. 8.33 ± 1.99, respectively, P = .785), were similar between troponin (+) and troponin (-) groups. Left ventricle end-systolic diameter (3.2 ± 0.78; 3.50 ± 0.74 vs. 3.2 ± 0.78, respectively, P = .031), left ventricle end-systolic volume (55.57 ± 32.17 vs. 38.28 ± 13.63, respectively, P = .013), left ventricle end-diastolic volume (115.31 ± 49.54 vs. 91.23 ± 20.57, respectively, P = .042), the rate of early systolic lengthening (65.7% vs. 28%, respectively, P = .001), the duration of early systolic lengthening (24.02 ± 31 ms vs. 15.56 ± 30.19 ms, respectively, P = .009), and the SYNTAX score (16 ± 11 vs. 10 ± 10, respectively, P = .023) were higher in the troponin (+) group. Furthermore, a significant correlation was found between early systolic lengthening and SYNTAX score (r = 0.43, P < .001). Conclusion: The rate and duration of early systolic lengthening were higher in patients in the troponin (+) group. Early systolic lengthening is related to SYNTAX score in patients with non-ST-elevation ACS. [ABSTRACT FROM AUTHOR]

Objective: Increased pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) are important prognostic factors in patients with heart transplantation (HT). It is well known that severe mitral regurgitation increases pulmonary pressures. However, the European Society of Cardiology and the 6th World Symposium of pulmonary hypertension (PH) task force redefined severe functional mitral regurgitation (FMR) and PH, respectively. We aimed to investigate the effect of severe FMR on PAP and PVR based on these major redefinitions in patients with HT. Methods: A total of 212 patients with HT were divided into 2 groups: those with severe FMR (n=70) and without severe FMR (n=142). Severe FMR was defined as effective orifice regurgitation area ≥20 mm2 and regurgitation volume ≥30 mL where the mitral valve was morphologically normal. A mean PAP of >20 mm Hg was accepted as PH. Patients with left ventricular ejection fraction ≤25% were included in the study. Results: The systolic PAP, mean PAP, and PVR were higher in patients with severe FMR than in those without severe FMR [58.5 (48.0--70.2) versus 45.0 (36.0--64.0), p<0.001; 38.0 (30.2--46.6) versus 31.0 (23.0--39.5), p=0.004; 4.0 (2.3--6.8) versus 2.6 (1.2--4.3), p=0.001, respectively]. Univariate analysis revealed that the severe FMR is a risk factor for PVR ≥3 and 5 WU [odds ratio (OR): 2.0, 95% confidence interval (CI): 1.1--3.6, p=0.009; and OR: 3.2, 95% CI: 1.5--6.7, p=0.002]. The multivariate regression analysis results revealed that presence of severe FMR is an independent risk factor for PVR ≥3 WU and presence of combined pre-post-capillary PH (OR: 2.23, 95% CI: 1.30--3.82, p=0.003 and OR: 2.30, 95% CI: 1.25--4.26, p=0.008). Conclusion: Even in the updated definition of FMR with a lower threshold, severe FMR is associated with higher PVR, systolic PAP, and mean PAP and appears to have an unfavorable effect on pulmonary hemodynamics in patients with HT.

Elevated left ventricular end-diastolic pressure (LVEDP) is associated with adverse outcomes among those patients with ST-elevation myocardial infarction (STEMI).We aim to investigate the acute change of LVEDP in patients with STEMI and the relationship between LVEDP and early reperfusion parameters, such as ST-segment resolution (STR%) and myocardial blush grade (MBG). A total of 51 consecutive patients with STEMI who had undergone successful primary percutaneous coronary intervention (pPCI) with TIMI flow grade 3 were included in the study. LVEDP measurements were performed at the beginning (pre-pPCI LVEDP) and end of (post-pPCI LVEDP) the pPCI. MBG was defined after a successful pPCI; STR% was calculated 60 minutes after pPCI. The mean pre-pPCI LVEDP was 22.1 ± 4.8 mmHg and the post-pPCI LVEDP was 19.4 ± 4.8 mmHg. There was a mean 2.7±1.8 mmHg decrease in LVEDP values after pPCI which was statistically significant (95% CI -3.2, -2.2, p value< 0.001). Post-pPCI LVEDP median value was 19 mmHg. The patients were divided into two groups according to median value: there were 26 (51%) patients with post-pPCI LVEDP≤ 19 mmHg and 25 (49%) patients with post-pPCI LVEDP> 19 mmHg. STR% and MBG were significantly different between the two groups (p= 0.03 and p= 0.01). Post-pPCI LVEDP had a moderate negative correlation with MBG (r= -0.438) and STR% (r= -0.501). In this study, we demonstrated that primary PCI might substantially reduce the LVEDP level. Moreover, the LVEDP levels achieved after PCI might be associated with myocardial reperfusion, assessed by STR% on ECG and MBG during angiography. [ABSTRACT FROM AUTHOR]
