Large number of studies recently have been published regarding the prevalence of IAB and its associations with the risk of atrial fibrillation and ischemic stroke. Cardiovascular diseases are the leading causes of mortality in chronic kidney disease (CKD).

Comparison of aortic pressures and aortic elastic properties between patients with end-stage renal disease and healthy controls.

Background: Current evidence indicates that vascular calcification plays an essential role in the development of cardiovascular diseases in end-stage renal disease (ESRD) patients.

The relationship between R wave peak time and left ventricular mass index in patients with end-stage renal disease on hemodialysis.

Purpose: Cardiovascular complications have been reported to be the main cause of mortality in patients with end-stage renal disease (ESRD). Although left ventricular hypertrophy is the most common clinical presentation of cardiac remodeling, cardiovascular complications may also include disturbances of the heart conduction system. The R wave peak time (RWPT) has been previously associated with left ventricular hypertrophy and myocardial ischemia.

Presence of fragmented QRS may be associated with complex ventricular arrhythmias in patients with essential hypertension.

Background: Ventricular arrhythmias (VAs) are frequent in hypertensive patients. Myocardial fibrosis is one of the components of left ventricular hypertrophy secondary to hypertension. Fragmented QRS (fQRS) on electrocardiography (ECG) has been shown to be a marker of myocardial fibrosis.

Missed unroofed coronary sinus.

Coronary sinus atrial septal defect (ASD) is a rare congenital cardiac anomaly, which might be difficult to diagnose. In this report, we describe a patient with small secundum ASDs and an associated large coronary sinus ASD, which had been missed at initial evaluation. The diagnosis of coronary sinus ASD was established by using transesophageal echocardiography after percutaneous closure of a small secundum ASD at another center.

Investigation of ICAM-1 levels in hypertensive patients with fragmented QRS complexes.

Fragmented QRS (fQRS) detected on a 12-lead electrocardiogram (ECG) has been demonstrated to be a marker of myocardial fibrosis. Intercellular adhesion molecule-1 (ICAM-1) is a protein which plays an important role in fibro-inflammatory processes. In this study, we aimed to investigate the relationship between ICAM-1 levels and the presence of fQRS in hypertensive patients.

Presence of fragmented QRS is associated with increased epicardial adipose tissue thickness in hypertensive patients.

Background: Epicardial adipose tissue (EAT) is a cardiometabolic risk factor, and its possible relationship with hypertension has been reported previously. Fragmented QRS (fQRS) detected on electrocardiography (ECG) has been demonstrated to be a marker of myocardial fibrosis. In this study, we aimed to investigate the relationship between the thickness of EAT, and presence of fQRS in hypertensive patients.

Relation of serum spondin-2 levels with cardiac morphology and inflammatory parameters in hemodialysis patients.

Purpose: Cardiovascular diseases are the leading causes of mortality in chronic kidney disease. Spondin-2 (SP-2), an intrinsic cardio-protective factor, prevents maladaptive remodeling. We aimed to determine the relation between serum SP-2 levels and cardiac morphology along with inflammatory parameters in hemodialysis (HD) patients.

A rare complication of percutaneous coronary intervention: Coronary pseudoaneurysm formation.

Coronary pseudoaneurysms (CPAs) are rare complications developed after percutaneous coronary interventions. They may cause stent thrombosis, distal embolization, and coronary rupture leading to cardiac tamponade. Therefore, high-risk CPA should be promptly treated after diagnosis.

Investigation of mindin levels in hypertensive patients with left ventricular hypertrophy and QRS fragmentation on electrocardiography.

Purpose: Mindin was associated with diabetic nephropathy, podocyte injury, colitis, allergic asthma, liver ischaemia and reperpusion injury and ischaemic brain injury. On the other hand, it was reported as a protective factor against obesity, cardiac hypertrophy, fibrosis and remodelling. Fragmented QRS complexes (fQRS) are markers of altered ventricular depolarisation owing to a prior myocardial scar and fibrosis.

Relation of Serum ADMA, Apelin-13 and LOX-1 Levels with Inflammatory and Echocardiographic Parameters in Hemodialysis Patients.

Cardiovascular diseases are the leading causes of mortality in patients with chronic kidney disease. Nitric oxide has a critical role in both endothelial dysfunction and the atherosclerosis process. We aimed to investigate the relationships between serum asymmetric dimethyl arginine (ADMA), LOX-1, and Apelin-13 levels, which are known to act over nitric oxide with endothelial dysfunction and cardiac morphology as well as with each other in hemodialysis patients.

Thrombus formation in the interrupted segment of the aorta.

Interrupted aorta is a very rare heart defect in which there is a gap between the ascending and the descending thoracic aorta. It is usually associated with other cardiac anomalies, including ventricular septal defect, ductus arteriosus, and truncus arteriosus. Severe cases present with serious complications such as hypertension, heart failure, or intracranial hemorrhage.
