Guidelines for the Evaluation and Management of Heart Failure Report of the American College of Cardiology/ American Heart Association Task Force on Practice Guidelines (Committee on Evaluation and Management of Heart Failure)

Abstract: It is becoming more apparent each day that despite a strong national commitment to excellence in health care, the resources and personnel are finite. It is, therefore, appropriate that the medical profession examine the impact of developing technology and new therapeutic modalities on the practice of cardiology. Such analysis, carefully conducted, could potentially have an impact on the cost of medical care without diminishing the effectiveness of that care. To this end, the American College of Cardiology and the American Heart Association in 1980 established a Task Force on Assessment of Diagnostic and Therapeutic Cardiovascular Procedures (now the ACC/AHA Task Force on Practice Guidelines) with the following charge: The task force of the American College of Cardiology and the American Heart Association shall develop guidelines relative to the role of new therapeutic approaches and of specific noninvasive and invasive procedures in the diagnosis and management of cardiovascular disease. The task force shall address, when appropriate, the contribution, uniqueness, sensitivity, specificity, indications, contraindications and cost-effectiveness of such diagnostic procedures and therapeutic modalities. The task force shall emphasize the role and values of the developed guidelines as an educational resource. The task force shall include a chair and eight members, four representatives from the American Heart Association and four representatives from the American College of Cardiology. The task force may select ad hoc members as needed upon the approval of the presidents of both organizations. Recommendations of the Task Force are forwarded to the President of each organization. The members of the task force are Melvin D. Cheitlin, MD, Kim A. Eagle, MD, Timothy J. Gardner, MD, Arthur Garson, Jr, MD, MPH, Raymond J. Gibbons, MD, Richard P. Lewis, MD, Robert A. O’Rourke, MD, Thomas J. Ryan, MD, and James L. Ritchie, MD, Chair. The Committee to Develop Guidelines on the Evaluation …

Do gender-based differences in presentation and management influence predictors of hospitalization costs and length of stay after an acute myocardial infarction?

Abstract: Previous studies have reported conflicting results on gender differences in the management of acute myocardial infarction (AMI) and have not evaluated hospital length of stay or costs. To determine gender-based differences in presentation, management, length of stay, costs, and prognosis after AMI, we studied 561 patients with AMI. Women were older, had systemic hypertension, diabetes mellitus, and a non-Q-wave AMI more frequently, whereas more men smoked cigarettes. Predictors of coronary angiography were: male gender (RR 1.9; 95% CI 1.2 to 3.1), chest pain at presentation (RR 1.8; 95% CI 1.0 to 3.3), recurrent angina (RR 4.1; 95% CI 2.5 to 6.8), admission via the emergency room (RR 0.2; 95% CI 0.1 to 0.3), and younger age. Gender did not predict mortality. Among presenting features, the predictors of length of stay were diabetes, prior coronary bypass and prior coronary angioplasty in men, and age alone in women. Pulmonary edema and need for coronary bypass during the hospital course were predictors of length of stay in men only. Among presenting features, predictors of cost were diabetes in men and congestive heart failure in women. Predictors of cost during hospitalization for men were pulmonary edema, coronary angiography, intraaortic balloon pump use, and coronary bypass; for women, they were peak levels of creatine kinase and coronary bypass. Thus, predictors of length of stay and hospitalization costs differ based on gender. Efforts at cost containment may need to be gender-specific.

Sex Differences in Perioperative and Long-term Cardiac Event–Free Survival in Vascular Surgery Patients An Analysis of Clinical and Scintigraphic Variables

Abstract: Background Little information is available regarding the occurrence of perioperative and late cardiac events in women with vascular disease. The current study was performed to examine whether sex-specific differences exist in these outcomes in a large population of vascular surgery patients and to determine the value of clinical and dipyridamole thallium variables in predicting myocardial infarction and cardiac death. Methods and Results Preoperative dipyridamole thallium imaging was performed in 567 vascular surgery patients, including 380 men and 187 women. The incidence of nonfatal myocardial infarction and cardiac death was noted during the perioperative period and during a follow-up period of 50±5 months. Fixed and reversible thallium perfusion abnormalities were more common in men than in women (P<.001 and P=.004, respectively). Perioperative cardiac event rates were similar in men and women, 8.4% and 7.5%, respectively (P=.07). A transient thallium defect was associated with an increased risk of ca...

Syncope: diagnosis of cardiac and noncardiac causes.

Abstract: Syncope is a sudden and temporary loss of consciousness not caused by trauma or seizures. Patients age 65 and older are at elevated risk of syncope-related falls and sudden cardiac death. Cardiovascular causes are generally electrical (ie, arrhythmias) or mechanical (obstruction of central circulation at a cardiac valve or major vascular structure). Noncardiovascular causes include orthostatic hypotension, vasovagal reaction, micturition, carotid sinus hypersensitivity, and neurologic (eg, TIAs). Many causes of syncope can be diagnosed from a thorough history and physical exam. More extensive testing--ECG, Holter monitoring, electrophysiology study--may be indicated for selected patients with unexplained syncope and an unremarkable evaluation.
