“…Using m-mode echocardiography from the parasternal short-axis view at the level of papillary muscles we measured LV end-diastolic diameter (LVEDD) and end-systolic diameter (LVESD). LVEF was measured using the biplane Simpson's method of discs by 2D echocardiography from the apical 4-and 2-chamber views [16,17].…”

Background: Cardiac rehabilitation programs reduce cardiovascular events and mortality in ischemic heart disease patients. The aim of this study was to assess gender differences among ischemic heart disease patients enrolled in a cardiac rehabilitation program regarding adherence to the program, as well as, changes in clinical, laboratory, and echocardiographic parameters. Results: A prospective study that included 30 men and 30 women with stable ischemic heart disease who had been totally revascularized by percutaneous coronary intervention. Patients were enrolled in a 12-week cardiac rehabilitation program. Assessment of demographics, anthropometric measurements, risk factors, and functional capacity was performed. Lipid profile, glycated hemoglobin, and left ventricular ejection fraction were assessed. Assessments were performed at baseline and after completion of the program. Time to enrollment in the program was prolonged for women 39.17 ± 40.49 vs. 19.77 ± 10.26 days (p = 0.014). At baseline, more women were diabetic (p = 0.004), hypertensive (p = 0.02), had a larger waist circumference (p = 0.022), a higher BMI (p = 0.011), and higher HbA1c (p = 0.033). More men were active smokers (p < 0.001). After completion of the program, it was found that men attended 19.1 ± 4.77 (79.6%) sessions compared to 15.7 ± 5.72 (65.4%) sessions for women (p = 0.015). Women had more reduction in diastolic BP − 10.93 ± 8.94 vs. − 5.47 ± 12.57 mmHg (p = 0.058). The magnitude of reduction in resting heart rate was significant in men (p = 0.018) but not in women (p = 0.376). The magnitude of reduction in serum total cholesterol and triglycerides was more in men (p = 0.018 and p = 0.014). Women showed more reduction in HbA1c (p = 0.052). Conclusion: Men are more adherent to cardiac rehabilitation programs. Recruitment of women is significantly delayed. Women have a higher cardiovascular risk burden in the form of prevalence of diabetes, hypertension, and obesity. Completion of a cardiac rehabilitation program causes a reduction in BMI, waist circumference, blood pressure measurements, total cholesterol, triglycerides, LDL-C, HDL-C, HbA1c, and LVEDD with an increase in LVEF in both genders. Men show more reduction in resting HR, total cholesterol, and triglyceride levels while women show more reduction in diastolic BP and HBA1c.

“…In particular, unsatisfactory results were obtained in the recent MITRA-FR trial. 1 In patients with severe secondary MR, the rate of death at 1 year did not differ significantly between patients who underwent percutaneous mitral valve repair and those who received medical therapy alone. 1 On the other hand, the COAPT trial found that among patients with moderateto-severe or severe MR who remain symptomatic despite optimal medical therapy, MitraClip (Abbott Vascular, Santa Clara, CA) implantation resulted in a lower rate of hospitalization for heart failure and lower all-cause mortality within 2 years of follow-up compared with those referred to medical therapy alone.…”

“…Measurement of linear dimensions at the midventricular level (LV-D2) better re ects the ellipsoid geometry of the LV cavity and provides a more accurate estimate of LV mass and size as compared with the traditionally recommended basal level 13 . In addition, the LV contains obliquely-oriented myo bers super cially, longitudinally-oriented myo bers in the subendocardium, and predominantly circular bers in between.…”

Background: Choosing a suitable cardiac cycle to measure cardiac chamber dimensions and wall thickness can be a more accurate assessment of cardiovascular disease.Methods: Cardiac CT was performed on 137 patients for suspected coronary disease. The parameters of left atrium (LA), left ventricle (LV), right atrium (RA), and right ventricle (RV), as well as the wall thickness of LV were measured in different cardiac phases. The general linear mixed model was used to analyze differences in different phases and the correlation between these parameters and traditional risk factors. ROC analysis was performed to estimate LA enlargement. Results:The dimensions of LA, RA, and LV wall thickness achieved the maximum at the phase of 35%–45%, and the dimensions of LV and RV reached the maximum at 95%–5%. Whereas, the changes of LA-B (antero-posterior diameter), LV-D1 (basal dimension), RA-B (minor dimension) and RV-D2 (mid cavity dimension) were relatively more stable during the cardiac cycle. The maximum LA-B diameter(95%CI 36.92,38.48mm), LV-D1 diameter(95%CI 44.36,45.83mm), RA-B diameter(95%CI 48.75,50.61mm), and RV-D2 diameter(95%CI 30.83,32.84mm) and the maximum interventricular septum thickness( 95%CI 10.79,11.51mm) was acquired. Heart rate (HR) and smoking were potential indicators of LVD2 (mid cavity dimension), while HR and LV myocardial mass were potential indicators of LVD3 (apical-basal dimension). In phase 45%, the cut-off value of LA-A with 77.57mm has high specificity.Conclusion: Cardiac chamber dimensions and wall thickness vary with the cardiac phase. Choosing the adaptive cardiac phase for evaluating these parameters obtained by cardiac CT could provide a more accurate clinical measurement.
