An obese 61-year-old man with a history of heroin abuse was brought to the hospital after he had fallen onto his buttocks on a sidewalk. He was able to stand initially, but weakness and numb-ness in his legs rendered him suddenly unable to walk or prevent himself from voiding. He denied abdominal or back pain. His medical history included asthma, chronic obstructive pulmonary disease, and hypertension.

In recognition of Valentine's Day, we present 2 incidental heart-shaped findings we encountered within the hearts of 2 patients during 2-dimensional transthoracic echocardiographic studies.

Faint-Free Blood Draws

With patients who say that they usually faint when blood is drawn or when given an injection, have them lie down and tell them that they "cannot faint when lying down." Whether for physiological or psychological reasons, patients usually do not faint when this is done.

To help answer the question of Mary Ellen Lewis, PA-C, about her patient with a low-density lipoprotein (LDL) cholesterol level of 120 mg/dL and a high-density lipoprotein (HDL) cholesterol level of 100 mg/dL(CONSULTANT, June 2007), I would like to describe my approach to the treatment of dyslipidemia.

A 62-year-old man presents with painful cramps in his left lower leg that began about 6 months earlier and have recently become more frequent. The cramps occur with vigorous walking and cease when he stops for several minutes.

When angiotensin-converting enzyme (ACE) inhibitors were first discovered, they were a welcome addition to the antihypertensive armamentarium. Since then, many more benefits of these drugs have been found: they slow the progression of diabetic nephropathy, abate the sequelae of heart failure when systolic dysfunction is present, and reduce the level of proteinuria in patients with nephrotic syndrome.

In his article, "Heart Failure: Part 1, Diagnosis and Staging" (CONSULTANT, July 2007), why did Dr W. H. Wilson Tang omit central venous pressure and circulation time as means of diagnosing congestive heart failure? Is it possible that the simplicity and accuracy of these 2 tests, which can establish the diagnosis in 5 or 10 minutes in any hospital room-or physician's examining room-have been forgotten since the advent of testing of natriuretic peptide levels (which, as Dr Tang notes, "also increase in response to other noncardiac processes")?

For 4 days, a 34-year-old pregnant woman had dyspnea and right-sided chest pain. She denied fever, chills, sweats, cough, lower extremity pain, and edema. Surgical and social histories were unremarkable. She was taking progesterone and clomiphene citrate for the past 6 months for assisted reproduction.

Over the past 20 years, the treatment armamentarium for diabetes has greatly expanded: 8 different classes of non-insulin drugs and 8 different types of insulin are now available. The newer classes of agents include disaccharidase inhibitors, thiazolidinediones, meglitinides, glucagonlike peptide analogs, and dipeptidyl peptidase IV inhibitors.

Interatrial septal aneurysm (IASA) and patent foramen ovale (PFO)-either alone or coexisting-are a frequent cause of cryptogenic cerebral and/or peripheral thromboemboli. The IASA plus PFO combination has been shown to confer higher risk, particularly in adults aged 45 years or younger. Therefore, recognition and documentation of these 2 abnormalities during an echocardiographic (transthoracic or transesophageal) study, when performed for other indications, is essential.

A 68-year-old woman with hypertension complains of intermittent dyspnea and light-headedness. She is asymptomatic during the evaluation. Vital signs are normal, but an irregularly irregular pulse is noted on examination as well as on the telemetry monitor. The 12-lead ECG is shown here; the ECG machine printout reads "atrial fibrillation." The patient has no history of this arrhythmia.
