What is causing extremely elevated amino terminal brain natriuretic peptide in cancer patients?

High levels of B-type natriuretic peptide in cancer patients are poorly studied. Previously published data suggest that they are not related to fluid overload and are encountered mostly in solid cancers. The authors investigated the distribution of amino terminal pro-brain natriuretic peptide (NT-proBNP) between hematologic and solid organ malignancies and the relationship of NT-proBNP with volume status in oncologic patients.

Routine invasive versus conservative management strategies in acute coronary syndrome: time for a "hybrid" approach.

The acute coronary syndrome is most often caused by plaque rupture and can result in a variety of clinical conditions. There are two general strategies (early invasive versus conservative) currently employed in the treatment of unstable angina or non-ST elevation myocardial infarction. Pooled data from recent clinical trials have demonstrated that high-risk patients benefit from a routine or early invasive approach while certain low-risk subgroups have similar outcomes with a conservative approach.

Aldosterone antagonists in heart failure.

Aldosterone antagonists represented by nonselective spironolactone and mineralocorticoid-selective eplerenone are approved for treatment of symptomatic heart failure with reduced systolic function. Their cardioprotective, antifibrotic, and antiarrhythmic effects have been proven in animal experiments, and their effects on morbidity and mortality have been demonstrated in randomized clinical trials. Yet, they remain the most underutilized of all classes of medications for heart failure, primarily because of fear of hyperkalemia.

Women tolerate drug therapy for coronary artery disease as well as men do, but are treated less frequently with aspirin, beta-blockers, or statins.

Background: Women have worse morbidity, mortality, and health-related quality-of-life outcomes associated with coronary artery disease (CAD) compared with men. This may be related to underutilization of drug therapies, such as aspirin, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, or statins. No studies have sought to describe the relationship of gender with adverse reactions to drug therapy (ADRs) for CAD in clinical practice.

Gender differences in the value of ST-segment depression during adenosine stress testing.

Previous studies have suggested that ST-segment depression with adenosine myocardial perfusion imaging (MPI) may be a marker of significant coronary artery disease (CAD). It is unclear if the significance of ST depression differs between men and women. We investigated the diagnostic accuracy of ST-segment depression with adenosine radionuclide MPI as a marker of significant CAD in men and women.
