- Several studies have shown training induced morphological changes in the heart. Our aim was to assess how frequent, low-intensity exercise (walking and cycling) influences heart function and morphology in abdominally obese women. Fifty women with abdominal obesity (mean age 47.0 +/- 7.5 years, waist circumference (WC) 103.2 +/- 7.8 cm), free of cardiovascular problems were recruited. They were equipped with a bicycle and pedometers and instructed to start commuting in a physically active way for 6 months. Evaluation of cardiac function and morphology was performed using echocardiography (ECHO) before and after 6 months of training. The subjects increased significantly their daily physical activity. After 6 months, there was a significant decrease in WC (from 103.3 +/- 7.9 to 100.8 +/- 8.4 cm, P = 0.0003), in systolic and diastolic blood pressure (126.8 +/- 15.2 to 120.4 +/- 14.5 mmHg, P = 0.0001, and 79.8 +/- 7.8 to 77.8 +/- 8.4 mmHg, P = 0.0006, respectively). ECHO showed an increase in the right ventricular (RV) systolic longitudinal function expressed as tricuspid annular motion from 22.00 +/- 3.30 to 23.05 +/- 3.59 mm, P = 0.015; and a similar trend in left ventricular (LV) mitral annular motion, which increased from 13.09 +/- 1.53 to 13.39 +/- 1.47 mm, P = 0.070. Cycling was associated with reductions in LV systolic and RV diastolic dimensions, whereas walking was not associated with any changes in the ECHO-variables. A reduction in WC by frequent, low-intensity exercise in abdominally obese women is associated with decrease in blood pressure and improved longitudinal RV systolic function.

- Aims: To investigate the association between intima-media thickness of brachial and common carotid arteries and factors of the coagulation- and fibrinolysis-system with left ventricular diastolic dysfunction in patients with a previous myocardial infarction. Patients and methods: One hundred and twenty three patients, men (76%) and women (24%) aged between 32and 81 years with a history of previous acute myocardial infarction were included. B-mode ultrasound of common carotid and brachial arteries and echocardiography with tissue Doppler imaging (TDI) were evaluated. Factors of the coagulation- and fibrinolysis-system were also measured. Results: In patients with previous myocardial infarction, late diastolic filling time was significantly and positively associated with log Prothrombin fragment 1 + 2 (P < 0.001) and with calculated intima-media area (cIMa) of the both common carotid and brachial arteries (P < 0.05). Mitral early-to-late flow velocity ratio (E/A) was significantly and negatively associated with log Prothrombin fragment 1 + 2 (P < 0.001), total cholesterol and cIMa of the both common carotid and brachial arteries (P < 0.05). Moreover both late diastolic filling time and mitral E/A correlated significantly with age and systolic blood pressure. In stepwise multiple regression analysis, log Prothrombin fragment 1 + 2 remained the only variable with independent significant correlation to late diastolic filling time and mitral E/A. Conclusions: In a population sample of patients with myocardial infarction, late diastolic filling time and mitral E/A were associated with cIMa of common carotid and brachial arteries, systolic blood pressure, and prothrombin fragment 1 + 2, suggesting a relationship between diastolic dysfunction, thrombin generation and atherosclerosis.

- Controversy exists regarding whether all patients with acute myocardial infarction (AM!) benefit from angiotensin-converting enzyme inhibitors (ACEIs). We examined the association between ACEI treatment and mortality in a large, unselected population of patients with AMI. The present study included 105,224 patients with AMI who were not treated with ACEIs on admission. A logistic regression analysis, including 33 variables, calculated a propensity score for each patient to estimate the probability of receiving ACEIs at discharge, given the background. The association between ACEI treatment at discharge and the 1-year outcome was evaluated in prespecified subgroups using the Cox regression analyses, adjusting for the propensity score and medications at discharge. A total of 38,395 patients (36.5%) received ACEIs at discharge. After adjustment, ACEI treatment was associated with a 24% reduction in mortality (relative risk 0.76, 95% confidence interval 0.73 to 0.80). The benefit was largest in patients with a history or present signs of heart failure. In patients without heart failure, a significant benefit of ACEI treatment was seen only in patients with renal dysfunction (relative risk 0.69, 95% confidence interval 0.54 to 0.88). In the whole group, the risk of AMI decreased by 7% (relative risk 0.93, 95% confidence interval 0.90 to 0.96), with a larger effect seen in patients with ST-segment elevation AMI or systolic left ventricular dysfunction. In conclusion, in unselected patients with AMI, ACEI treatment was associated with a reduction in 1-year mortality, mainly in patients with heart failure or renal dysfunction, and a small reduction in the risk of reinfarction, mainly in patients with ST-segment elevation AMI or systolic left ventricular dysfunction.
