Angiosarcoma of the right atrium presenting as collapse.

Pericardial effusion may originate from a wide variety of underlying pathology. Primary cardiac malignancy should always be considered as a rare underlying cause. Angiosarcoma is the most common cardiac malignancy, which often arises as a mass in the right atrium.

High-dose beta-blockers and tight heart rate control reduce myocardial ischemia and troponin T release in vascular surgery patients.

Background: Adverse perioperative cardiac events occur frequently despite the use of beta (beta)-blockers. We examined whether higher doses of beta-blockers and tight heart rate control were associated with reduced perioperative myocardial ischemia and troponin T release and improved long-term outcome.

Methods And Results: In an observational cohort study, 272 vascular surgery patients were preoperatively screened for cardiac risk factors and beta-blocker dose.

Significance of acute versus chronic troponin T elevation in dialysis patients.

Introduction: Cardiac troponin T (cTnT) is often elevated in hemodialysis (HD) patients without acute coronary syndrome (ACS). The aim was to assess the predictive value for mortality of pre-dialysis cTnT in asymptomatic patients. If patients became symptomatic during follow-up, cTnT was followed to assess its diagnostic value for ACS.

A dose-finding study of fondaparinux in patients with non-ST-segment elevation acute coronary syndromes: the Pentasaccharide in Unstable Angina (PENTUA) Study.

Objectives: In this dose-finding study, we sought to compare fondaparinux with enoxaparin in patients with acute coronary syndromes (ACS).

Background: Fondaparinux is a synthetic pentasaccharide that selectively inhibits activated clotting factor X. It has been demonstrated as effective in preventing thromboembolic complications in orthopedic surgery.

Cardiac and metabolic effects in patients who present with a multinodular goitre.

Twenty-six consecutive patients who presented with clinically euthyroid multinodular goitre were studied for an overnight fasting serum lipid profile and 24 h Holter monitoring. Mean serum TSH was 0.6 +/- 0.
