Percutaneous coronary intervention (PCI) of total chronic coronary occlusions (CTOs) still remains a major challenge in interventional cardiology. There is little knowledge in the literature about differences in CTO-PCI between diabetic and nondiabetic patients in the era of third-generation drug-eluting stents (DESs). In this study, we analyzed the impact of diabetes mellitus (DM) on procedural characteristics, complications, and acute outcomes in a cohort of 440 patients.

Background: Percutaneous coronary intervention (PCI) of total chronic total occlusion (CTO) still remains a major challenge in interventional cardiology. Recanalization of in-stent CTO (IS-CTO) is associated with inferior success rates. This present study aims to comparatively evaluate the acute outcome of patients with IS-CTO and de novo CTO.

Unlabelled: Percutaneous coronary intervention (PCI) of total chronic coronary occlusion (CTO) still remains a major challenge. The prevalence of a CTO has been reported to be up to 30% among patients with a clinical indication for coronary angiography. Progress has been made with further advanced interventional techniques and continuously sophisticated interventional tools.

The use of a novel irrigated multipolar ablation and mapping catheter for pulmonary vein isolation in patients with atrial fibrillation (AF) has demonstrated reasonable acute success rates and short procedure times, however, long-term outcome data are limited. The aim of this study was to analyze the long-term efficacy of this novel ablation system utilizing a reduced power setting for safety purposes.A total of 89 patients with paroxysmal (63 of 89 patients; 71%) or persistent AF underwent PVI with a reduced power setting of maximum 20 Watts (W) unipolar radiofrequency energy and 30 seconds in duration.

Background: Percutaneous coronary intervention (PCI) of total chronic coronary occlusion (CTO) still remains a major challenge. Insignificant data are reported in the literature about gender differences in CTO-PCI in the era of new drug-eluting stents. In this study we analysed the impact of gender on procedural characteristics, complications and acute results.

Background: Percutaneous coronary intervention (PCI) of total chronic coronary occlusion (CTO) still remains a major challenge in interventional cardiology. To predict the probability of a successful intervention different scoring systems are available. We analyzed in this study the validity of two scoring systems, the Japanese CTO score (J-CTO score) and the newly developed Clinical and Lesion-related score (CL Score).

Background: In patients with aortic stenosis (AS), increased afterload induces changes in left ventricular (LV) geometry to preserve a normal ejection fraction (EF). Nevertheless, myocardial dysfunction may occur in spite of a normal EF. Global longitudinal strain (GLS) analysis can detect subtle contractile dysfunction at a pre-clinical stage.

Aims: Left ventricular diastolic dysfunction is considered a precursor of diabetic cardiomyopathy, while diabetic cardiovascular autonomic neuropathy is associated with an increased risk of mortality. This study aimed to evaluate the association between left ventricular diastolic dysfunction and cardiovascular autonomic neuropathy, both diagnosed according to the current guidelines.

Methods: We evaluated 145 patients referred for an elective coronary angiography, 52 of whom had Type 2 diabetes and 48 had impaired glucose tolerance, while 45 subjects had normal glucose tolerance.

Background/objectives: Guidelines recommend screening all patients with cardiovascular disease by oral glucose tolerance test (OGTT). Due to its time-consuming protocol, costs and overall inconvenience performance of OGTT is limited in cardiological routine. Thus, we aimed to identify easily available parameters that could help to reduce the numbers of OGTT needed.

Background: In the era of fibrinolysis, women suffered from higher early and late mortality rates than men after acute ST-elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention (PCI) has been determined to be the most effective therapy strategy in STEMI. It is not clear if female gender is an independent predictor of a worse long-term prognosis among patients who were systematically treated with PCI.

Objective: The development of diastolic dysfunction (DDF) is multifactorial. Possible mechanisms include metabolic disturbances, myocardial fibrosis, chronic inflammation and endothelial dysfunction. Recognizing early stages of DDF may help to identify patients at risk of developing symptomatic DDF.

Background: Diabetes mellitus (DM) has reached epidemic proportions and is an important risk factor for heart failure (HF). Left ventricular diastolic dysfunction (LVDD) is recognized as the earliest manifestation of DM-induced LV dysfunction, but its pathophysiology remains incompletely understood. We sought to evaluate the relationship between proinflammatory cytokine levels (TNF-alpha, IL-6) and tissue Doppler derived indices of LVDD in patients with stable coronary artery disease.

It has been suggested that matrix-metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of metalloproteinases (TIMPs) play a major role in the regulation of myocardial remodeling. Myocardial extracellular matrix (ECM) is highly susceptible to ischemic injury in acute myocardial infarction (AMI).We measured serum levels of TIMP-1 in the early hours of AMI to study the kinetics of these enzymes in an early ischemic phase.

Objective: The development of left ventricular remodelling (LVR) after acute myocardial infarction (AMI) is a predictor of heart failure and mortality. The extracellular matrix (ECM) is highly susceptible to ischaemic injury. Laminin and collagen type VI (CVI) contribute to ECM formation in the infarct zone.

Diastolic dysfunction is associated with a high rate of morbidity and mortality and has a high prevalence in patients with diabetes. Aim of the study was to investigate the prevalence of diastolic dysfunction in patients with newly detected glucose metabolism disorder (GMD) submitted for coronary angiography. Oral glucose tolerance test, echocardiography, and tissue Doppler imaging were performed in patients referred to coronary angiography.
