Insights
Obesity significantly impacts cardiovascular diseases, yet overweight individuals with existing conditions show a better prognosis, a phenomenon known as the obesity paradox. This review explores obesity
Area of Science:
- Cardiology
- Endocrinology
- Public Health
Background:
- Obesity is a global epidemic linked to numerous comorbidities like hypertension, diabetes, and cardiovascular diseases.
- Obesity adversely affects cardiovascular risk factors, structure, and function, increasing the risk of heart failure, coronary heart disease, and sudden cardiac death.
- Despite these risks, an obesity paradox suggests better outcomes for overweight/obese patients with established cardiovascular disease.
Purpose of the Study:
- To summarize the adverse effects of obesity on cardiovascular disease risk factors and pathogenesis.
- To review the obesity paradox and explore potential explanations for observed outcomes.
- To discuss the role of weight reduction in preventing and treating cardiovascular diseases.
Main Methods:
- Literature review of studies examining obesity, cardiovascular disease risk factors, and patient outcomes.
- Analysis of data related to the obesity paradox in conditions such as hypertension, heart failure, and coronary heart disease.
- Synthesis of current evidence on weight reduction strategies for cardiovascular disease prevention and treatment.
Main Results:
- Obesity exacerbates cardiovascular disease risk factors and contributes to the development of various cardiovascular conditions.
- The obesity paradox is consistently observed across multiple cardiovascular diseases, indicating better prognoses for overweight/obese individuals.
- Explanations for the paradox remain under investigation, with factors like inflammation, metabolic profiles, and treatment responses being explored.
Conclusions:
- Obesity poses significant risks for cardiovascular health, yet paradoxically offers a survival advantage in certain established cardiovascular diseases.
- Further research is needed to fully understand the mechanisms behind the obesity paradox and its clinical implications.
- The role and efficacy of weight reduction interventions in cardiovascular disease prevention and management require careful consideration.
Abstract:
Obesity has reached global epidemic proportions in both adults and children and is associated with numerous comorbidities, including hypertension (HTN), type II diabetes mellitus, dyslipidemia, obstructive sleep apnea and sleep-disordered breathing, certain cancers, and major cardiovascular (CV) diseases. Because of its maladaptive effects on various CV risk factors and its adverse effects on CV structure and function, obesity has a major impact on CV diseases, such as heart failure (HF), coronary heart disease (CHD), sudden cardiac death, and atrial fibrillation, and is associated with reduced overall survival. Despite this adverse association, numerous studies have documented an obesity paradox in which overweight and obese people with established CV disease, including HTN, HF, CHD, and peripheral arterial disease, have a better prognosis compared with nonoverweight/nonobese patients. This review summarizes the adverse effects of obesity on CV disease risk factors and its role in the pathogenesis of various CV diseases, reviews the obesity paradox and potential explanations for these puzzling data, and concludes with a discussion regarding the current state of weight reduction in the prevention and treatment of CV diseases.
