Prognostic value of C-reactive protein/albumin ratio in hypertensive COVID-19 patients.

Objectives: The aim of this study was to investigate the relationship between the C-reactive protein/albumin ratio and the prognosis of hypertensive COVID-19 patients.

Methods: It was designed as a single center retrospective study. PCR positive COVID-19 patients who were followed up in the intensive care unit (ICU) and received antihypertensive treatment were included in the study.

Hydroxychloroquine/azithromycin treatment, QT interval and ventricular arrhythmias in hospitalised patients with COVID-19.

Background: Hydroxychloroquine (HCQ) and azithromycin (AZM) are widely used in off-label treatment of novel coronavirus disease (COVID-19). However, cardiac safety of these drugs is still controversial in COVID-19. Therefore, we aimed to evaluate association of HCQ or HCQ + AZM treatment regimens, corrected QT (QTc) interval and malignant ventricular arrhythmias in hospitalized patients.

Implications of continuous positive airway pressure on heart rate variability in patients with obstructive sleep apnea: Does gender matter?

Objective: This study was designed to determine the effectiveness of continuous positive airway pressure (CPAP) treatment on the improvement of heart rate variability (HRV) and whether gender plays a role in HRV in patients with mode-rate to severe obstructive sleep apnea syndrome (OSAS).

Methods: Consecutive patients with recently diagnosed moderate to severe OSAS underwent continuous synchronized electrocardiographic monitoring and were prospectively considered for inclusion in the study. HRV was analyzed before starting CPAP therapy and 1 year thereafter.

Strenuous exercise induced syncope due to coronary artery anomaly.

Coronary artery anomalies are among the neglected topics in cardiology. Anomalous origin of the left main coronary artery from the right sinus of valsalva is a rare coronary anomaly observed in 0.15% of patients.

The effect of long-term continuous positive airway pressure treatment on systolic and diastolic function in patients with obstructive sleep apnoea syndrome: a five year observational study.

Objective: Evaluation of the long-term effects of continuous positive airway presure (CPAP) on mean heart rate and left ventricular systolic and diastolic parameters in obstructive sleep apnea syndrome (OSAS) using conventional and tissue Doppler techniques.

Methods: This prospective cohort study is designed to evaluate the long-term effects of CPAP treatments in normotensive OSAS patients. Initially 40 patients aged from eighteen to fifty five with documented OSAS syndrome were evaluated within one month of CPAP treatment.

Increased serum leptin concentrations in patients with chronic stable angina pectoris and ST-elevated myocardial infarction.

Leptin is an adipocytokine that is produced mainly by adipose tissue; it is also identified in atherosclerotic lesions in human coronary atherosclerosis. However, the relation of serum leptin concentrations to ischemic heart disease (IHD) is still obscure. The aims of the present study were to investigate serum leptin concentrations in patients with ST-elevated myocardial infarction (STEMI) and with chronic stable angina pectoris (CSAP) and to evaluate the possible correlations of leptin to other atherosclerotic risk factors; including serum high sensitive C-reactive protein (Hs-CRP), serum homocysteine, and fibrinogen concentrations.

The effect of tirofiban on ST segment resolution in patients with non-ST elevated myocardial infarction.

ST segment resolution in ST elevated myocardial infarction has independent predictive value for congestive heart failure and death at 30 days. ST segment depression in unstable angina pectoris (UAP) and non-ST elevated myocardial infarction (NSTEMI) predicts high risk of MI and death and may discriminate patients likely to have greater benefit from aggressive antithrombotic and interventional therapy. This study assessed the effect of tirofiban added to conventional treatment on ST segment resolution in NSTEMI patients.

[Evaluation of diastolic function by transmitral color M-mode flow propagation velocity in hypertensive patients].

Objective: Diastolic dysfunction is considered as the most important cause of heart failure and morbidity in hypertensives. This study was designed to evaluate the relationship between the transmitral diastolic color M-mode flow propagation velocity (FPV) and left ventricular relaxation by using Doppler echocardiography.

Methods: In the present study, thirty-nine patients (21 male, 58.

[The effects of clarithromycin treatment on cardiac events in acute coronary syndrome patients].

Objective: The assessment of short duration early clarithromycin treatment on major cardiac events in acute coronary syndrome patients.

Methods: One hundred and thirteen patients with acute coronary syndrome had been enrolled in the study in a prospective manner. Fifty-seven of 113 patients received peroral clarithromycin 1g/day for 14 days in addition to standard therapy.

[Doppler index of myocardial performance and its relationship with mitral E wave deceleration time in acute Q-wave myocardial infarction].

Objective: The objectives of the study were to assess myocardial systolic and diastolic functions by myocardial performance index (MPI) and its relationship with E - wave deceleration time (DT) in early phase of acute Q-wave myocardial infarction (MI).

Methods: We performed nongeometric Doppler-derived echocardiography to assess combined systolic and diastolic functions using myocardial performance index in 50 patients with acute Q-wave MI at early phase of events, (25 pts with anterior MI and 25 pts with inferior MI). The index is defined as the sum of the isovolumic contraction and isovolumic relaxation times divided by ventricular ejection time and was obtained by Doppler measurement from the diastolic mitral inflow and left ventricular outflow velocity-time intervals.
