Prevalence of coronary artery calcification in a multiethnic population in Angola.

Unlabelled: This article aims to study the prevalence of coronary artery calcification and associated factors in a multiethnic population in Angola.

Methods: A descriptive, cross-sectional observational study was carried out in a private clinic in Angola. For this purpose, information was collected from sociodemographic and biological data.

Prevalence of coronary artery anomalies in 295 coronary computed tomography angiographies performed in Angola: Challenges and difficulties.

The present article describes the prevalence of coronary artery anomalies (CAAs) in patients undergoing coronary CT angiography at a private clinic in Luanda, Angola, and the clinical and angiotomographic characteristics of the two patients with CAAs. These anomalies are uncommon and constitute a significant challenge in resource-poor countries.

[High-degree atrioventricular block induced by Prinzmetal angina].

We present the case of a 46-year-old woman with episodes of chest pain with ST-T segment elevation and paroxysmal high-degree atrioventricular block and syncopal episodes. Coronary angiography revealed no significant atheromatous lesions. The patient was treated with nitrates and calcium channel blockers but syncopal episodes with atrioventricular block persisted.

Very late coronary stent thrombosis after discontinuation of antiplatelet therapy.

Percutaneous transluminal coronary angioplasty (PTCA) with stent placement is widely used to achieve myocardial revascularization in patients with symptomatic ischemic heart disease and significant coronary artery stenosis. Drug-eluting stents are used in most patients undergoing percutaneous angioplasty. Stent thrombosis is an uncommon but serious complication, manifested mostly by sudden death or acute ST-elevation myocardial infarction.
