Factors Affecting Smoking Cessation After Acute Myocardial Infarction.

Objective: Persistent smoking after acute myocardial infarction is associated with an increased risk of recurrent cardiovascular events. Our aim was to determine the changes in smoking habits in patients after acute myocardial infarction and evaluate the factors affecting smoking cessation.

Material And Methods: A total of 322 patients who had an acute myocardial infarction while smoking were included in the study.

The evaluation of the metabolic and autonomic predictors of cardiovascular diseases in relation to prostatic hyperplasia symptoms.

Objectives: High prevalence of cardiovascular diseases is present in benign prostatic hyperplasia patients. Risk prediction models were developed for early identification of these cardiovascular risks. We aimed to evaluate cardiovascular metabolic and autonomic predictors in relation to lower urinary tract symptoms' severity evaluated by the IPSS score.

The relationship of benign prostatic hyperplasia's symptoms severity with the risk of developing atrial fibrillation.

Background: Attention is drawn to the increased incidence of atrial fibrillation (AF) in benign prostatic hyperplasia (BPH) patients recently. Early predicting of AF in these patients can help in decreasing its clinical consequences. The aim of our study is to determine the association between BPH symptoms and AF predictors atrial electromechanical delay (AEMD) and the P-wave dispersion (PWD).

Variation of Tpeak-end, corrected Tpeak-end, QT, and corrected QT intervals, Tpeak-end/QT, Tpeak-end/corrected QT ratios and heart rate variability according to decades in the healthy male subjects aged between 30 and 79 years.

Background: Heart rate variability (HRV) is a predictor of cardiac autonomic functions. Ventricular repolarization markers can indicate ventricular arrhythmias. We aimed to evaluate variations of HRV and these repolarization markers in five healthy male groups between age 30 and 79 years according to decades.

Variation of the T-wave peak-end interval and heart rate variability values in healthy males and females at various hours of the same day, and relationship of them.

Background: The prolongation of repolarization time between the myocardial epicardium and endocardial cells is closely related to malignant ventricular arrhythmias. The purpose of our study was to compare repolarization markers, namely, T-wave peak-end interval (Tp-e), QT, corrected QT (QTc), Tp-e/QT, Tp-e/corrected QT (QTc), and Heart Rate Variability (HRV) values in healthy men and women and to investigate their daily variations.

Methods: A total of 74 male and 78 female participants, being a government employee, and having no health problems, were included in the two study groups (males and females).

The relationship between systolic pulmonary arterial pressure and Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios in patients with newly diagnosed chronic obstructive pulmonary disease.

Introduction: The risk of sudden cardiac death (SCD) and arrhythmias has been shown to be common in chronic obstructive pulmonary disease (COPD) subjects. We aimed to evaluate the markers of arrhythmia such as QT, QTc (corrected QT), Tp-e, and cTp-e (corrected Tp-e) intervals, Tp-e/QT ratio, and Tp-e/QTc ratio in newly diagnosed COPD subjects in both right and left precordial leads.

Materials And Methods: The study group consisted of 74 subjects with obstructive respiratory function tests (RFTs).

Weekly variation of the QT dispersion in healthy subjects and in patients with coronary heart disease.

Background: A circadian and seasonal variation of QT dispersion (QTd) has been shown in healthy individuals. Nevertheless, no data exist regarding the weekly influences on the QTd in healthy individuals and in patients with coronary heart disease (CHD).

Design: This study was designed to determine whether there is a weekly variability of QTd in healthy individuals and in patients with CHD.

Influence of haematological parameters before coronary angioplasty on subsequent restenosis.

Objectives: Restenosis is the major limitation of coronary interventions occurring in nearly a third of the patients undergoing percutaneous transluminal coronary angioplasty (PTCA) with no single, definite predictor demonstrated in an individual patient. Platelets are known to play an important role in the pathogenesis of subsequent restenosis.

Methods And Results: In a prospective study, follow-up coronary angiographies were performed in 102 consecutive patients with stable angina who underwent a successful PTCA for single-vessel coronary artery disease.
