LOS ANGELES -- For heart failure patients, the "obesity paradox" of better survival rates with increasing heft appears to hold true during acute hospitalization as well, according to a large registry study.

SAN FRANCISCO -- B-type natriuretic peptide, a marker of myocardial stretch, predicted adverse coronary outcomes and mortality in patients with stable coronary heart disease, researchers reported.

CINCINNATI -- The occurrence rate of cerebral hemorrhage associated with the use of Coumadin (warfarin) quintupled in the 1990s, paralleling an increase in blood-thinner's prescriptions according to researchers here.

LONDON -- For early-stage breast cancer that is HER2-positive, a year of adjuvant Herceptin (trastuzumab) significantly improves overall survival two years later without undue cardiotoxicity, researchers here said.

ANN ARBOR, Mich. -- When a sophisticated electrocardiogram test appears to rule out the need for an implanted cardioverter-defibrillator in ischemic cardiomyopathy, the results are frequently ignored, according to researchers here and Cincinnati.

LOS ANGELES -- Performance measures adopted by the government and JCAHO to gauge hospital quality of care for heart failure have little impact on survival during the critical early post-discharge period, researchers here reported.

The introduction of effective antiretroviral therapy has resulted in dramatic clinical benefits for those persons who have access to it. Adherence to such therapy has emerged as both the major determinant and the Achilles' heel of this success. Many patients have levels of adherence too low for durable virologic control.

The authors report a case of adult-onset acute lymphoblastic leukemia (ALL) presenting with a right upper lobe infiltrate associated with acute fibrinous and organizing pneumonia (AFOP), which resolved spontaneously during the course of chemotherapy.

On a warm August day, a 79-year-old man is hospitalized because of progressive lethargy over the past week. Previously, he was alert and able to converse. He has no chest pain, dyspnea, or cough.

Q:Is periodic laboratory monitoring recommended for patients withosteoarthritis who are receiving long-term cyclooxygenase-2 (COX-2)inhibitor therapy and who have no GI or renal symptoms? Similarly,is laboratory monitoring recommended for women who take a selectiveCOX-2 inhibitor to alleviate menstrual cramps (eg, rofecoxib, 50 mg/d,3 to 5 days per month)?--Sarita Salzberg, MDColumbus, Ohio

Q:Do evidence-based data support combination therapy with anangiotensin-converting enzyme (ACE) inhibitor and an angiotensin IIreceptor blocker (ARB)?

Your middle-aged patientwith type 2 diabetes wishesto start a weight-trainingprogram. What recommendationswill you offerhim? Another diabetic patient hasperipheral neuropathy; which exercisesare safest for her?

An 83-year-old woman is hospitalized for treatment of deep venous thrombosisin her left leg. She underwent left hip replacement surgery 2 months earlier.At that time, mild anemia (hemoglobin level, 10 g/dL) was noted, and iron therapywas initiated. An iron panel obtained shortly after the hip surgery revealeda serum iron level of 80 μg/dL, a transferrin level of 360 mg/dL, and a ferritinlevel of 50 ng/mL.

Lately I have heard that "tissue ACE" properties are important in endothelial remodelingand in the prevention of myocardial infarction and stroke.

Q:Should hypertensive patients be discouraged from participating inmoderate to vigorous exercise?A:On the contrary, most patients with sustained hypertension should bestrongly encouraged to exercise regularly at moderate to vigorous levels.Randomized controlled clinical trials have demonstrated that increasedphysical activity can lower blood pressure (BP) and delay or prevent the developmentof hypertension and thus the need for antihypertensive medication.1In addition, physical activity can help reduce cardiovascular risk factors by improvinglipid profiles and reducing weight and blood glucose levels. In elderlypersons, exercise is associated with improvements in osteoporosis, depression,and physical functioning, as well as an enhanced sense of well-being.

Is treatment recommended for high-normalblood pressure (BP)-say, 135/88 mm Hg-ina postmenopausal woman?

I have read that mental confusion and paranoia may be potential side effects ofcertain angiotensin-converting enzyme (ACE) inhibitors.

What is the risk of dementia in patients who have had an ischemic stroke?

A 20-year-old woman has had several episodes of syncope since she enteredcollege 2 months earlier. Although 1 or 2 episodes were associated with exercise,most were not. All occurred at times of surprise and/or emotional stress:she fainted twice when the bell rang at the end of a test, once after her alarmclock suddenly awakened her in the morning, and once when she received adisturbing phone call from home.

In this compact clinical guide, the author presents detailed prescribing advice forall types of cardiac patients. The first chapters are devoted to the principal classesof cardiac drugs: β-blockers, angiotensin-converting enzyme inhibitors, angiotensinII receptor blockers, calcium antagonists, and diuretics. These chapterscover such topics as indications, contraindications, adverse effects, interactions,dosages, differences between the available agents in a given class, and how tochoose the most appropriate agent from a class for a particular patient. Chapterson the management of the various cardiac disorders-hypertension, angina, acutemyocardial infarction, heart failure, arrhythmias, cardiac arrest, infective endocarditis,and hyperlipidemia-comprise the core of the book. There are also chapterson antiplatelet agents, anticoagulants, and thrombin inhibitors; and the use ofcardiac drugs during pregnancy and lactation. The sixth edition features a newchapter on recent clinical trials, new American Heart Association cardiac arresttreatment algorithms, current hypertension management guidelines, and expandeddrug administration and dosage tables. Numerous tables, charts, algorithms,and graphs accompany the text.
