The CART ring was superior to the Apple Watch in automated AF detection with fewer unclassified ECGs, but neither device should serve as a definitive diagnostic tool.
Chest Pain: 10 Common Myths and Mistakes
June 1st 2007ABSTRACT: Atypical clinical presentations in the quality, intensity, and radiation of pain are common in patients with acute coronary syndromes. Women with an acute myocardial infarction (AMI) are more likely to have atypical symptoms, such as dyspnea, than men. A history of acute anxiety or a psychiatric diagnosis does not preclude the possibility of an acute coronary event in a patient with chest pain. The clinical response to a GI cocktail, sublingual nitroglycerin, or chest wall palpation does not reliably identify the source of pain. Over-reliance on tests with poor sensitivity, such as the ECG, or on the initial set of cardiac biomarkers will miss many patients with MI. Serial troponin levels obtained at 3- to 6-hour intervals are recommended to evaluate the extent of myocardial damage. Coronary angiography that detects mild non-obstructive disease does not exclude the possibility of sudden plaque rupture and acute coronary occlusion.
BREAKING NEWS: Jerry Falwell Dies at 73

Postpartum pulmonary arterial hypertension
May 1st 2007Patients with congenital heart disease and pulmonary arterial hypertension (PAH) are at risk for severe deterioration during pregnancy and delivery. We discuss the case of a 38-year-old woman who presented to the emergency department complaining of dyspnea 6 days after giving birth to her first child via cesare- an section. When PAH is untreated, maternal mortality may exceed 50%, but aggressive PAH treatment offers improved outcomes. Moreover, initial improvement in functional status made with parenteral prostanoids can be maintained with combination oral therapy.
Preventing Reinfarction: Basic Elements of an Effective Cardiac Rehabilitation Program
May 1st 2007ABSTRACT: Patients who experience an acute myocardial infarction (MI) are at very high risk for recurrent cardiovascular events. Both site-supervised and home-based cardiac rehabilitation programs can effectively reduce all-cause and cardiovascular mortality. Start risk factor reduction as soon as possible; pharmacotherapy is best initiated while patients are still in the hospital. All patients who have had an MI should receive aspirin, an angiotensin-converting enzyme inhibitor, and a ß-blocker, unless these agents are contraindicated or are not tolerated. Prescribe aggressive lipid-lowering therapy to bring patients' low-density lipoprotein cholesterol levels to below 70 mg/dL. For smokers, quitting is the single most important change they can make to reduce future risk of MI.
Anticoagulation in Paraplegic Patients
April 1st 2007The role of anticoagulation in the treatment of patients who have been permanently immobilized as a result of neurological impairments is unique. Patients with spinal injuries have been comprehensively studied, and the data are very clear: the risk of DVT falls sharply 4 to 6 months after the injury and onset of immobility.
