Carotid Artery Atherosclerotic Profile as Risk Predictor for Restenosis After Coronary Stenting.

Background: The incidence of restenosis of the coronary artery after a bare-metal stent implant has been lower than in simple balloon angioplasty; however, it still shows relatively high rates.

Objective: The aim of this study was to find new risk indicators for in-stent restenosis using carotid ultrasonography, that, in addition to the already existing indicators, would help in decision-making for stent selection.

Methods: We carried out a cross-sectional prospective study including 121 consecutive patients with chronic coronary artery disease who had undergone percutaneous coronary intervention with repeat angiography in the previous 12 months.

Evaluating respiratory musculature, quality of life, anxiety, and depression among patients with indeterminate chronic Chagas disease and symptoms of pulmonary hypertension.

Introduction:: Chagas disease (CD) is progressive and incapacitating, especially when cardiopulmonary function is affected. For example, respiratory muscle weakness can cause dyspnea upon exertion and fatigue, which may be exacerbated when it is associated with pulmonary hypertension (PH). The present study aimed to evaluate respiratory musculature, quality of life, anxiety, and depression among patients with indeterminate chronic CD and symptoms of PH.

Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy.

Unlabelled: Hepatic encephalopathy (HE) is a cognitive disturbance characterized by neuropsychiatric alterations. It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts. The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.

Percutaneous coronary intervention in single coronary artery in a patient with high-risk unstable angina.

In the present case, we report the performance of coronary angioplasty with stent implantation in the right coronary artery of a patient with high-risk unstable angina and single coronary artery originating from the right coronary sinus. The anterior descending and circumflex arteries originated separately from the proximal third of the right coronary artery. This is a rare coronary anomaly and few reports of percutaneous coronary intervention are found in the literature.

Frequency of coronary artery disease in patients with renal artery stenosis without clinical manifestations of coronary insufficiency.

Atherosclerotic renal artery stenosis (RAS) and coronary artery disease (CAD) arise from the same multiple risk factors. The purpose of this study was to assess the frequency of previously undiagnosed CAD in patients with angiographically confirmed RAS, by conducting coronary arteriography in the same setting. Of 57 consecutive patients referred for renal arteriography on clinical grounds during a 14-month period, 28 had no RAS and 6 had RAS, but previously documented CAD.
