Mid-term clinical outcomes of new generation drug-eluting stents for treatment of diffuse coronary artery disease.

Objective: Diffuse coronary artery disease (CAD) is a challenging issue in clinical cardiology practice. There are limited data about percutaneous revascularization in these patients.

Methods: This study was an observational clinical evaluation.

Successful treatment of massive pulmonary embolism with reteplase.

Unexpected and unexplained out-of-hospital cardiac arrests have a poor prognosis. Difficulties encountered during the differential diagnosis phase may delay the administration of specific treatment for treatable and reversible causes of cardiac arrest. Massive pulmonary embolism is a reversible cause of cardiac arrest, but without proper management it has a high mortality rate.

Cardiac autonomic nervous dysfunction detected by both heart rate variability and heart rate turbulence in prediabetic patients with isolated impaired fasting glucose.

Objective: Cardiac autonomic nervous dysfunction (CAND), a severe complication of diabetes, has also been shown to affect prediabetic patients. The role of isolated impaired fasting plasma glucose (IFG), a subtype of prediabetes, is not clear in the pathogenesis of CAND. The aim of this study was to examine the relationship between isolated IFG and cardiac autonomic function using heart rate variability (HRV) and heart rate turbulence (HRT) indices derived from 24-h Holter electrocardiogram recordings.

Which is responsible for cardiac autonomic dysfunction in non-diabetic patients with metabolic syndrome: Prediabetes or the syndrome itself?

Aims: Cardiac autonomic dysfunction (CAD) is associated with both prediabetes and metabolic syndrome (MS). Heart rate variability (HRV) and heart rate turbulence (HRT) are reliable 24-h Holter-ECG findings of cardiac autonomic function. This study aimed to investigate the relation between MS and its components and CAD using HRV and HRT.

Effects of three month nasal continuous positive airway pressure treatment on electrocardiographic, echocardiographic and overnight polysomnographic parameters in newly diagnosed moderate/severe obstructive sleep apnea patients.

The objective of the study was to determine the effects of nasal continuous positive airway pressure (nCPAP) therapy on left ventricular (LV) function and electrocardiographic parameters in newly diagnosed moderate/severe obstructive sleep apnea (OSA) patients without cardiovascular comorbidities and medical treatments. We examined 44 patients who underwent overnight polysomnography together with 24-hour Holter electrocardiography, cardiopulmonary exercise testing including heart rate recovery at 1 minute (HRR-1), echocardiography, surface electrocardiography, and those who were diagnosed with moderate/severe OSA apnea--hypopnea index ≥ 15. After 3 months of nCPAP treatment, the above-mentioned examinations were repeated.

Arrhythmogenic evidence for epicardial adipose tissue: heart rate variability and turbulence are influenced by epicardial fat thickness.

Background: Epicardial adipose tissue (EAT) is a local source of various hormones, cytokines, and vasoactive substances affecting the myocardium. EAT contains abundant ganglionic plexi that interact with the autonomic nervous system. Evidence of the association between EAT and arrhythmia is limited, with the exception of atrial fibrillation.

Epicardial adipose tissue thickness and plasma homocysteine in patients with metabolic syndrome and normal coronary arteries.

Background: Increased epicardial adipose tissue thickness and plasma homocysteine levels are associated with Metabolic Syndrome (MS) and coronary artery disease. The majority of patients with MS have subclinical or manifest coronary artery disease. The aim of this study was to evaluate the relationship between MS and plasma homocysteine levels and epicardial adipose tissue thickness in subjects without epicardial coronary artery disease.

Hyperhomocysteinemia in a young woman presenting with acute myocardial infarction: Case report.

Homocysteine (Hcy), a sulfur-containing amino acid that is formed by demethylation of dietary methionine to cystein. Elevated homocysteine level is known to be associated with coronary artery disease. We present a case of acute myocardial infarction in a 25-year-old woman, associated with hyperhomocysteinaemia.

[Saphenous vein graft disease: causes, prevention, and contemporary treatment strategies].

Coronary bypass graft surgery provides symptomatic relief and a long life expectancy for most patients with coronary artery disease who have suitable vessels. Although arterial conduits are becoming more popular, saphenous vein grafts (SVG) are still frequently used in coronary artery bypass surgery since they are readily available, especially in emergency situations. However, SVG tend to degenerate over time, as nearly half of them develop significant stenosis and nearly 40% of them become completely occluded within a decade.

Hyperacute anterior myocardial infarction in a patient with dextrocardia and situs inversus.

Dextrocardia with situs inversus is an uncommon congenital condition in which the major visceral organs are reversed. The clinical diagnosis and electrocardiographic localization of myocardial infarctions in these patients remain a great challenge unless dextrocardia is recognized. A 50-year-old male with known dextrocardia and situs inversus presented with acute chest pain radiating to the right arm.

Sirolimus-Versus Zotarolimus-Eluting Stents in Acute Coronary Syndromes With C Type Left Anterior Descending Artery Lesions: A Three-Year Clinical Follow-Up.

Background: Drug-eluting stents have improved the efficacy of percutaneous coronary intervention and made it the preferred therapy in the treatment of ischemic heart diseases including acute coronary syndromes. The objective of the study was to compare the clinical efficacy and safety of sirolimus-eluting stent with that of zotarolimus-eluting stent following percutaneous coronary intervention for acute coronary syndrome patients with C-type left anterior descending stenosis.

Methods: A total of 154 acute coronary syndrome patients with C-type lesions in the left anterior descending artery, requiring a stent > 28 mm in length, were randomized into two groups to receive either sirolimus- (n = 74) or zotarolimus-eluting stent (n = 80).

Acute myocardial infarction and subacute stent thrombosis associated with cabazitaxel: a case report.

Case: Although newer cancer treatments and supportive care treatments have led to vast improvements in the management of complications associated with cancer treatment, sometimes they might cause serious side effects such as coronary artery disease, myocardial infarction and heart failure. These complications may occur any time during or after chemotherapeutics. In this report we present a patient with prostate cancer who experienced myocardial infarction and stent thrombosis probably caused by cabazitaxel -a new chemotherapeutic agent- administration.

Effect of obstructive sleep apnea on heart rate, heart rate recovery and QTc and P-wave dispersion in newly diagnosed untreated patients.

Introduction: Obstructive sleep apnea syndrome (OSAS) is associated with autonomic dysfunction, whereas increased heart rate (HR), HR recovery time (HRR-1), QT-corrected interval (QTc) and P-wave dispersion (Pd) are associated with cardiovascular events. The aim of the current investigation was to clarify the influence of OSAS severity on these cardiac parameters.

Methods: Ninety newly diagnosed and untreated patients with OSAS underwent overnight polysomnography and cardiopulmonary exercise testing, including HRR-1, echocardiography, 24-hour Holter electrocardiography, surface electrocardiogram (ECG) and measurement of several metabolic parameters.

A rare and avoidable complication of percutaneous coronary intervention: stent trapped in the left main coronary artery and its unusual treatment.

Entrapment of catheter components during cardiac interventions is rare but can cause life-threatening complications and sometimes requires emergency surgical treatment. This case study describes a 52-year-old male who had unstable angina pectoris and underwent stent insertion into the left circumflex artery. Unfortunately, the coronary stent and the balloon catheter were trapped while crossing the angulated segment between the left circumflex and left main coronary artery.

Hematologic parameters and angiographic progression of coronary atherosclerosis.

Hematologic parameters have prognostic importance in cardiovascular disease. However, the relation between atherosclerosis progression and hematologic parameters is not well defined. A total of 394 patients requiring repeat coronary angiography were included in the study.

Interventricular septal rupture after myocardial infarction despite early percutaneous coronary intervention.

Ventricular septal rupture (VSR) complicating acute myocardial infarction (AMI) is a serious clinical problem with high mortality rate due to cardiogenic shock or prolonged hemodynamic compromise. Despite multiple improvements in medical, interventional and surgical techniques, early and long-term prognosis after AMI related VSR still remain unpromising. We report a patient in whom an acute VSR was diagnosed 7 days after an anterior myocardial infarction treated with early primary percutaneous coronary intervention (pPCI).

Incidence, clinical characteristics, and 4-year follow-up of patients with isolated myocardial bridge: a retrospective, single-center, epidemiologic, coronary arteriographic follow-up study in southern Turkey.

Introduction: Myocardial bridge is a rare coronary anomaly that is generally considered to be benign. The true incidence and long-term prognosis are still under debate. Therefore, we investigated the prevalence and prognosis of patients with isolated myocardial bridge in our center.

Two-year outcome of Turkish patients treated with Zotarolimus versus Paclitaxel eluting stents in an unselected population with coronary artery disease in the real world: a prospective non-randomized registry in southern Turkey.

Background: Our purpose was to investigate the clinical outcomes of Zotarolimus- and Paclitaxel-eluting stents in Turkish patients with coronary artery disease (CAD). In general, the outcome of drug-eluting stent (DES) placement has a proven efficacy in randomized trials. However, the difference in efficacy between the Zotarolimus and Paclitaxel-eluting stents in unselected Turkish patients is controversial.

A severe coarctation of aorta in a 52-year-old male: a case report.

Aortic coarctation is a congenital malformation of the aorta usually diagnosed and corrected early in life. Long-term survival is exceptional in patients with untreated aortic coarctation. In this case report, we present a late diagnosis of aortic coarctation in a 52-year-old male.
