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.

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).

Significant stenoses of twin circumflex arteries accompanied by heart failure: a rare coronary artery anomaly.

Although coronary artery anomalies may cause some clinical symptoms, most are incidentally discovered as benign findings on coronary angiograms. A circumflex coronary artery anomalously originating from the right sinus of Valsalva is the most common coronary anomaly. However, a double circumflex coronary artery, both stenotic in their mid portions, resulting in symptomatic heart failure is a rare clinical and angiographic condition.
