As an adaptive response to myocardial ischemia, coronary collateral circulation (CCC) plays an important role in obstructive coronary artery disease (CAD). The association between serum thyroid hormone levels and development of CCC was investigated in the present study.

We aimed to investigate the role of the NLR to predict ventricular remodeling (VR) in patients with anterior ST-elevation myocardial infarction (STEMI) who were treated with primary percutaneous coronary intervention.
Subjects And Methods: We prospectively included 274 consecutive anterior STEMI patients.
Objective: Epicardial fat thickness (EFth) is associated with both left ventricular hypertrophy (LVH) and diastolic dysfunction. However, the effect of EFth on myocardial performance is not known. The aim of this study was to investigate the relationship between EFth and tissue Doppler myocardial performance index (TD-MPI), which incorporates both systolic and diastolic left ventricular (LV) function, in newly diagnosed hypertension (HT) patients.

Introduction: Despite major advances in stent technology and antithrombotic therapy, the development of stent thrombosis continues to be a major problem in patients who have undergone percutaneous coronary intervention (PCI). Although a few studies have investigated the relationship between early stent thrombosis and platelet activity, the relationship between acute stent thrombosis (AST) (within the first 24 h) and platelet indices is unclear.
Aim: We investigated the relationship between AST development and platelet indices in acute coronary syndrome patients.
Aims: The optimal strategy for patients with isolated ostial bifurcation lesions has not yet been determined. We propose the modified flower petal technique for the treatment of Medina type 0,0,1 or 0,1,0 coronary bifurcation lesions.
Methods And Results: We selected 64 patients who had Medina type 0,0,1 or 0,1,0 coronary bifurcation lesions.
Objective: We proposed a new technique for the treatment of coronary bifurcation lesions, called jailed semi-inflated balloon technique (JSBT).
Background: Currently, provisional approach is recommended to treat most of coronary bifurcation lesions. However, it is associated with the risk of side branch (SB) occlusion after main vessel (MV) stenting due to plaque or carina shift into the SB.
Background: The prognostic importance of high-sensitivity cardiac troponin T (hs-cTnT) has recently been reported in patients with heart failure. The myocardial performance index (MPI), which combines parameters of both systolic and diastolic ventricular function, provides a better marker of left ventricular dysfunction in hypertensive patients with preserved left ventricular ejection fraction (LVEF).
Aim: We aimed to investigate the relationship between hs-cTnT and tissue Doppler-derived MPI in newly diagnosed hypertensive patients with preserved LVEF.
Background: Percutaneous recanalization of chronic total coronary occlusion (CTO) tends to show a positive effect on left ventricular remodeling and ejection fraction (LVEF). Coronary flow velocity reserve (CFVR) is an important diagnostic index of the functional capacity of coronary arteries. The aim of this study was to evaluate, by non-invasive CFVR, whether the blood flow of donor artery reverts to normal after CTO percutaneous coronary intervention (PCI).

Objectives: The aim of this study was to investigate the association between coronary flow reserve (CFR) and left ventricle (LV) geometric patterns in patients with newly-diagnosed diabetes mellitus (DM).
Study Design: We studied 116 patients with newly-diagnosed DM and 31 healthy control subjects. Echocardiographic examination was performed on all subjects.
Accessory mitral valve is a rare entity which is commonly detected in children. It might present as a cause for left ventricular outflow obstruction, aortic regurgitation or a source for thromboembolic event. Diagnosis is based on echocardiographic findings, transesophageally when possible.

Thoracic aortic intima-media thickness (IMT) was reported as an earlier marker of preclinical atherosclerosis than carotid IMT. However, the relationship between MPV and aortic IMT was not investigated.

However, the association between kidney function with SYNTAX Score (SS) has not been investigated in patients with stable CAD with normal to mildly impaired renal function. We aimed to investigate the association between kidney function with SS.

There is evidence from studies supporting the validity of mean platelet volume (MPV) as a marker of vascular risk and predictor of thrombotic complications. The aim of this study is to investigate the relationship between MPV and MBPS in hypertensive patients.

Aortic intima-media thickness (IMT) is an earlier marker than carotid IMT of preclinical atherosclerosis. However, there is a lack of researches on direct investigation of relevance between serum 25-hydroxyvitamin D (25(OH)D) and thoracic aortic IMT.

Coronary flow velocity reserve (CFVR) is a reliable marker of coronary endothelial function in diabetic patients. The aim of this study was to investigate the association between AD and CFVR in newly diagnosed diabetic patients.

Oxidative stress plays a critical role during ischemia as well as during the reperfusion phase following ST elevation myocardial infarction (STEMI). We sought to investigate the relationship between no-reflow with paraoxonase-1 (PON-1) activity and oxidative stress markers (total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), lipid hydro-peroxide (LOOH)) in patients with anterior STEMI undergoing primary percutaneous coronary intervention (PCI).

High density lipoprotein (HDL), a powerful antioxidant, protects low density lipoprotein (LDL) particles against oxidative stress. By limiting LDL oxidation, HDL plays an important role in preventing atherosclerosis (AS). The antioxidant effect of HDL is mostly associated with the paraoxonase (PON1) activity.

Stroke is the leading cause of disability worldwide. It is known that atrial fibrillation and left atrial enlargement contribute ischemic stroke, and mean platelet volume (MPV) increases in patients with ischemic stroke and atrial fibrillation. We aimed to determine whether higher MPV is associated with ischemic stroke in patients with sinus rhythm.

Aim: To evaluate the effect of different AV delay times on various LV systolic performances by using automated functional imaging (AFI) in patients with a DDD pacemaker and preserved LV systolic function.
Even a slight decrease in the glomerular filtration rate (GFR) is an independent risk factor for cardiovascular disease. Arterial stiffness, left ventricular hypertrophy and N-terminal pro-brain natriuretic peptide (NT-proBNP) are independent risk factors for cardiovascular disease, which are particularly common in end-stage renal disease. We aimed to evaluate the association between GFR with arterial stiffness, left ventricle mass (LVM) and NT-proBNP in hypertensive subjects with normal to mildly impaired renal function.

We investigated the association between serum bilirubin level and thoracic aortic intima-media thickness (IMT). The study population consisted of 417 patients without coronary artery disease, who underwent transesophageal echocardiography examination for various indications. The highest aortic IMT values were observed in the bilirubinlow group compared with the bilirubinhigh group (P < .

The increased prognostic accuracy of the high-sensitivity cardiac troponin T (hs-cTnT) assay vs the conventional cTnT assay has recently been reported in hypertensive patients. The authors aimed to investigate the significance of serum hs-cTnT marker for prediction of nondipper hypertension (HTN) in hypertensive patients. A total of 317 patients with newly diagnosed HTN were studied.
