Background: Essential hypertension (EH) is defined as a worldwide public health problem and one of the important risk factors for development of human coronary artery disease. Increased peripheral arterial resistance is one of the distinguishing characteristics of EH. The extracellular deposition of calcium in the arterial wall is defined as vascular calcification, which results in aortic stiffness and elevation of blood pressure.

Background: Gamma-glutamyl transferase (GGT) level was found to be elevated in plasma of patients with cardiovascular risk factors. The aim of our study was to assess the relationship between serum GGT levels and the occurrence of no-reflow as well as to evaluate the prognostic value of GGT in ST-segment elevation myocardial infarction (STEMI) population.
Methods And Results: One hundred sixty-eight consecutive patients with STEMI who underwent percutaneous coronary intervention (PCI) were enrolled in the study.

Aim: Pseudoexfoliation (PEX) syndrome, diagnosed by ocular examination, is a common disorder of the extracellular matrix. Previous studies have demonstrated accumulation of PEX material in the walls of blood vessels and myocardium. We aimed to investigate whether PEX is associated with cardiovascular involvement using carotid ultrasound measurements and myocardial tissue Doppler imaging (TDI).

Involvement of the tricuspid valve is extremely rare. A 62-year-old female was admitted with complaints of fever, fatigue, difficulty in breathing, and swellings in her legs.

Although such connections have been proposed to have a protective role against potential obstructive coronary artery disease, their functional significance is unclear. We report on a 53-year-old woman who presented with typical chest pain.

Objectives: We evaluated the procedural success and short-mid term results of stent implantation for aortic coarctation in adults.
Study Design: The study included 15 consecutive patients (9 women, 6 men; mean age 27±7 years; range 17 to 45 years) treated with stent implantation for aortic coarctation. Fourteen patients had native, one patient had recurrent coarctation.
We report on a 43-year-old woman who presented with shortness of breath and syncope due to massive pulmonary embolism. Transthoracic echocardiography showed signs of right ventricular overload, and contrast-enhanced chest computed tomography demonstrated filling defects in both main pulmonary arteries consistent with obstructing thrombi. Initially, thrombolytic therapy with recombinant tissue plasminogen activator was given, but shock was not resolved.

Study Design: The study was conducted prospectively in three centers in 483 consecutive patients (402 men, 81 women; mean age 56.5 ± 11.
Background: The prevalence of smoking is high in Turkey. However, there are no data available evaluating the differences between smokers and nonsmokers according to their sex in patients with acute myocardial infarction (AMI) in Turkey.
Hypothesis: The aim of the study was to determine the prevalence of smoking and its relationship to age, localization, and extension of coronary heart disease (CHD), and other risk factors in Turkish men and women with first AMI.
Background: Saphenous vein graft (SVG) disease is the major determinant of long term graft viability in patients undergoing coronary artery bypass graft (CABG) surgery. Although, platelets play a major role in this pathogenetic process the nature of this interaction has not been yet been clarified. Mean platelet volume (MPV) reflects platelet production rate and stimulation.

Objective: The aim of the study was to compare diagnostic accuracy of tissue Doppler imaging (TDI) and conventional Doppler echocardiography in diagnosis of left ventricular diastolic dysfunction in patients with cardiac syndrome X.
Methods: Our study was designed as cross-sectional study. In our study, we compared 35 patients with cardiac syndrome X (19 female, mean age 47.
Objective: We sought to determine whether nebivolol affects coronary endothelial function and exercise induced ischemia in patients with cardiac syndrome X (CSX).
Methods: The study protocol undertaken was based on a single-blind randomized controlled prospective study. After a 2-week washout period, 38 patients with cardiac syndrome X were randomized to receive either nebivolol 5 mg daily (n=19) or metoprolol 50 mg daily (n=19) in a single- blind design for 12 weeks.
Background: Free radical-mediated oxidative stress has been implicated in the etiopathogenesis of several disorders. The aim of this study was to elucidate the effect of treatment with nebivolol on the metabolic state of oxidative stress, and antioxidant status markers in patients with cardiac syndrome-X (CSX), additionally, to compare with the effect of metoprolol treatment.
Methods: Thirty patients, 17 female and 13 male, with CSX were enrolled in the study.
Objective: There is not enough available data in our country about the prevalence of risk factors for ST-elevation myocardial infarction (STEMI), which has the highest in-hospital mortality rate within subtypes of acute coronary syndromes. Therefore, in this study, we aimed to evaluate the prevalence of risk factors for STEMI in Central Anatolia, one of the regions with high risk for coronary heart disease (CHD).
Methods: This cross-sectional observational study included 1210 patients (962 men, 248 women) with the diagnosis of STEMI in 3 tertiary-medical centers in 3 cities in Central-Anatolia (Ankara, Konya, and Kayseri).
Background: The cause of myocardial ischemia and chest pain in patients with cardiac syndrome X (CSX) has been explained by mechanisms including endothelial dysfunction. CSX patients have higher levels of asymmetric dimethylarginine (ADMA) and increased mean common carotid intima-media thickness (C-IMT). Accordingly, this study was designed to examine C-IMT with its association serum endothelial function parameters in patients with CSX.

The independence of this association from other confounding factors has remained controversial. The possible contributory effect of HU to myocardial impairment produced by hypertension (HT), however, has not been clarified yet.

The importance of coronary artery ectasia (CAE) lies in the fact that in 85% of cases it is accompanied by atherosclerotic coronary disease. The present study was designed to investigate MPV values in CAE patients in comparison with individuals with normal coronary angiograms.
