Insights
Cardiac rehabilitation programs significantly improve lipid profiles in Iranian cardiovascular patients. These programs enhance total cholesterol, LDL, HDL, and triglycerides, with added benefits from antilipid medications.
Area of Science:
- Cardiology
- Preventive Medicine
- Public Health
Background:
- Cardiac rehabilitation programs (CRP) show benefits for cardiovascular disease (CVD) patients.
- The impact of CRP on lipid profiles in CVD patients remains unclear.
- This study focuses on the Iranian population.
Purpose of the Study:
- To evaluate the effect of a comprehensive CRP on the lipid profile of Iranian patients with cardiovascular disease.
- To assess improvements in biochemical, functional, and psychosocial parameters post-CRP.
Main Methods:
- A self-controlled descriptive study design was employed.
- 547 patients with documented coronary heart disease were evaluated before and after a 24-session CRP.
- Data collected between 1998 and 2003, including patients on antilipid drugs.
Main Results:
- CRP significantly improved total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) levels.
- CRP contributed to lipid normalization: 34.9% for TC, 17.7% for LDL, and 27.2% for TG (P<0.001).
- Antilipid drugs provided additional normalization: 9.7% for TC, 1.8% for LDL, and 7.3% for TG.
Conclusions:
- Comprehensive CRP effectively improves lipid profiles (TC, TG, LDL, HDL) in Iranian CVD patients.
- CRP benefits lipid profiles even without antilipid drugs.
- Antilipid therapy can further enhance the positive effects of CRP on lipid profiles.
Background:
Cardiac rehabilitation program (CRP) has been demonstrated to have beneficial effects on physical and mental functioning as well as on mortality of patients with cardiovascular diseases, but its exact effect on lipid profile of these patients is still vague. In this study we aimed to evaluate the effect of comprehensive CRP on lipid profile of the Iranian population.
Design:
Self-controlled descriptive study.
Methods:
We evaluated 547 patients with documented coronary heart disease before and after a 24-session CRP between 1998 and 2003. Some of them received antilipid drugs.
Results:
Except for diastolic blood pressure, all other biophysical, biochemical [total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG)], functional, and psychosocial parameters had significant response to CRP. We can attribute the normalization of lipid in these patients to CRP in combination with medications 34.9% for TC, 17.7% for LDL, and 27.2% for TG (P<0.001 for all). Antilipid drugs had some more effect in normalizing the TC (9.7%), LDL (1.8%), and TG (7.3%).
Conclusion:
Comprehensive CRP improves TC, TG, LDL, and HDL in Iranian patients with cardiovascular disease even without antilipid drugs, and antilipid therapy can boost this effect.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
