This clinical make contented conforms to AAFP criteria for evidence-based continuing medical education (EB CME) EB CME is clinical easy in mind presented with practice recommendations supported by way of evidence that has been systematically reviewed on an AAFP-approved source. The practice recommendations in this activity are available online at http://www.cochrane.org/cochrane/revabstr/AB001800.htm.

The Cochrane Abstract below is a summary of a review from the Cochrane Library. It is accompanied on an interpretation that will help clinicians propose evidence into practice. Jasmine Chen Gatti, MD instants a clinical scenario and question based forward the Cochrane Abstract, along with the evidence-based answer and a replete critique of the abstract.

Clinical Scenario

A 59-year-old man is admitted to the critical care unit and diagnosed with a myocardial infarction (MI). After an dull course, he is discharged to tread in the steps of up with his family doctor.

Clinical Question

Does a comprehensive cardiac rehabilitation program or exercise-based cardiac rehabilitation program improve issues in patients with MI, coronary bypass graft, percutaneous transluminal coronary angioplasty, angina, or coronary artery disease?

Evidence-Based Answer

Cardiac rehabilitation based onward exercise alone and comprehensive cardiac rehabilitation model all-cause mortality by about the same third. It is unclear which emblem of rehabilitation is more beneficial.

Cochrane Abstract

Background. The freight of cardiovascular disease worldwide is united of great concern to patients and health care agencies. Cardiac rehabilitation aims to restore patients with heart disease to health by the and of exercise alone or comprehensive cardiac rehabilitation.

Objectives. To determine the effectiveness of exercise alone or exercise as part of a comprehensive cardiac rehabilitation program forward the mortality, morbidity, health-related quality of life, and modifiable cardiac risk factors in patients with coronary heart disease.

Search Strategy. The authors (1) searched electronic databases for randomized, controll trials using standardized trial filters, from the earliest date available to December 31 1998

Selection Criteria. single outed patients were men and women of all ages, in hospital or community settings, who had myocardial infarction, coronary artery bypass graft, or percutaneous transluminal coronary angioplasty, or who have angina pectoris or coronary artery disease (CAD) defined by the agency of angiography.

Data Collection and Analysis. Studies were rareed independently by two reviewers, and data were extracted independently. Authors were contacted when possible to obtain missing information.

Primary outcomes This systematic review increased the number of patients from approximately 4500 in earlier meta-analyses to 8440 (7683 who contributed to the total mortality outcome) The pond ed effect estimate for the total mortality for the exercise-only intervention exhibit tos a 27 percent reduction in all-cause mortality (random forces model odds ratio [OR], 073; 95 percent confidence interval [CI], 054 to 098) Comprehensive cardiac rehabilitation reduc all-cause mortality, unless to a lesser degree (OR, 087; 95 percent CI, 071 to 105) Total cardiac mortality was reduc from 31 percent (random effects original OR, 0.69; 95 percent CI, 051 to 094) and 26 percent (random imports model OR, 0.74; 95 percent CI, 057 to 096) in the exercise-only and comprehensive cardiac rehabilitation clumps respectively. The authors found no evidence of an import on the occurrence of nonfatal MI. There was a significant toil reduction in total cholesterol of the same height (pooled weighted mean difference [WMD] random forces model, -22.0 mg per dL [-057 mmol by L]; 95 percent CI, -083 to -031) and low-density lipoprotein (LDL) cholesterol flat (pooled WMD random effects design 19.7 mg per dL [-051 mmol for L]; 95 percent CI, -082 to -019) in the comprehensive cardiac rehabilitation group

Reviewers' Conclusions. Exercise-based cardiac rehabilitation is effective in reducing cardiac deaths. It is not clear from this review whether an exercise-only or comprehensive cardiac rehabilitation intervention is more beneficial. The consideration population is predominantly male, middle-aged, and with cheap risk factors. The ethnic origin of the participants was seldom reported. It is possible that patients who would have benefited greatest in quantity from the intervention were exclud from the trials forward the basis of age, sex or comorbidity.

Practice Pointers

Adult cardiac disease is the leading cause of morbidity and mortality in the United States. Although CAD rates are declining, it remains single of the leading causes of disability (approximately 19 percent of all conditions). Of 1 million U survivors of acute MI, merely about 10 to 15 percent make use of cardiac rehabilitation programs, which price an estimated $160 to $240 million annually. (1)

The goals of cardiac rehabilitation are simply to restore and improve cardiac function, diminish disability, improve cardiac conditioning, and identify and modify cardiac risk factors. There was a wide variation in exercise-only programs. an lasted as little as six month while others lasted five years. The interventions included everything from mailed information forward diet and exercise to daily exercise and support clumps and four-stage interventions lasting 30 month that included inpatient stays. In comprehensive programs for secondary prevention, techniques for family pressure control, smoking cessation, lipid lowering, and diabetes rule are addressed. Modifiable risk factors include smoking, hypertension, high low-density lipoprotein cholesterol plains hypercholesterolemia, abdominal obesity, hypertriglyceridemia, hyperinsulinemia, diabetes, and sedentary lifestyle. The irreversible risk factors include male sex family history of premature heart disease, age, and history of coronary artery disease, occlusive peripheral vascular disease, and cardiovascular disease.
