Pulmonary artery pressures and right ventricular dimensions of post-COVID-19 patients without previous significant cardiovascular pathology.

Background: Pulmonary hypertension is a significant complication of COVID-19, but follow-up data on pulmonary artery pressure after recovery from COVID-19 are limited.

Objectives: To investigate pulmonary artery pressure and heart dimensions in post-COVID-19 patients without a history of significant cardiac pathology.

Methods: Data for 91 eligible adult patients were subjected to 2 analyses.

New steps in acute coronary syndrome and antihyperlipidemic treatment: Determination of statins and metabolites by liquid chromatography tandem mass spectrometry.

Our aim in this study was to develop a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the measurement of atorvastatin, rosuvastatin and their major metabolites, and furthermore to evaluate patients' adherence to statin therapy and to investigate the effect of statin therapy on various hematological and biochemical parameters. A simple protein precipitation was performed for the extraction of analytes and the extracted samples were injected directly. The levels of drugs and their metabolites were measured by the validated method in a total of 210 patients diagnosed with unstable angina pectoris (USAP), ST-elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (NSTEMI).

Distal transradial versus conventional transradial access in acute coronary syndrome.

Objective: Distal transradial access (TRA) has been recently introduced as an alternative access site for coronary angiography (CAG). Both procedures can be performed in cardiology clinics by interventional cardiologists. Although distal TRA is considered to be more difficult as it requires artery puncture and experienced cardiologists, it seems to be more advantageous because of the limited risk of arterial occlusion.

Prevalence and Characteristics of Coronary Artery Anomalies Using Invasive Coronary Angiography in 6237 Consecutive Patients in a Single Center in Turkey.

Background: Coronary artery anomalies (CAAs) include clinically and anatomically diverse types of congenital heart defects occurring in a complicated spectrum. The aim of the present study is to describe congenital anomalies of coronary arteries (CAs) and their variations, and also identify the prevalence of these anomalies in our center.

Methods: The study included a total of 6237 consecutive patients.

Focusing on a complete blood cell parameter: mean platelet volume levels may be a predictor of coronary slow flow.

Background: The relationship between increased mean platelet volume (MPV) and atherosclerosis is well known. In the present study, MPV in patients with coronary slow flow (CSF) and in cases with normal coronary anatomy (NCA) was investigated and compared with the aim of identifying the relationship between CSF and MPV.

Patients And Methods: We studied 40 patients previously determined via coronary angiography as having NCA and 40 patients with CSF in the coronary blood stream, as identified by thrombolysis in myocardial infarction square.

Comparision of effects of rosuvastatin versus atorvastatin treatment on plasma levels of asymmetric dimethylarginine in patients with hyperlipidemia having coronary artery disease.

Elevated plasma levels of asymmetric dimethylarginine (ADMA) are prevalent in patients with hypercholesterolemia and coronary artery disease. A total of 83 patients with hypercholesterolemia and angiographically documented mild coronary artery stenosis were randomized to rosuvastatin treatment (20 mg) or atorvastatin treatment (40 mg) once daily for 6 weeks after a 4-week dietary lead-in phase. Both statins decreased total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride levels effectively.

Elevated red blood cell distribution width in healthy smokers.

Objectives: Red blood cell distribution width (RDW) has been reported to be a marker of morbidity and mortality for some cardiovascular and pulmonary diseases. We aimed to evaluate RDW values in otherwise healthy smokers.

Study Design: Two hundred and twenty consecutive subjects with current smoking and 230 age- and gender-matched healthy subjects without smoking history were enrolled.

Deficiency of a new protein associated with cardiac syndrome X; called adropin.

The pathophysiology of cardiac syndrome X (CSX) is still unclear, but most patients with CSX have endothelial dysfunction. It has been shown that adropin uniquely effects the regulation of endothelial function. The purpose of the study was to evaluate the role of adropin in CSX.

An investigation of tenascin-C levels in rheumatic mitral stenosis and their response to percutaneous mitral balloon valvuloplasty.

Objective: The purpose of this study was to evaluate the tenascin-C levels in severe rheumatic mitral stenosis before and after percutaneous mitral balloon valvuloplasty (PMBV).

Subjects And Methods: Forty patients with severe mitral stenosis requiring PMBV and 20 age-matched healthy subjects were included in the study. The mitral valve areas, mitral gradients and systolic pulmonary artery pressure (sPAP) were measured by echocardiography.
