Key result
Caloric restriction may slow biological aging and potentially improve CV outcomes in healthy nonobese adults.
Why the study?
Cardiovascular aging involves adaptive structural and functional changes that increase susceptibility to myocardial ischemia and heart failure, motivating a review of its pathophysiology and therapeutic interventions.
Effect estimate: null (95% CI null)
p-value: p=null
Age-related vascular and myocardial adaptations increase the baseline risk for cardiovascular diseases like heart failure and ischemia.
May support caloric restriction to slow aging in nonobese adults; leaves open cardiovascular outcome benefits pending randomized trials.
Cardiovascular aging is a complex process of adaptive structural and functional changes over time. With advancing age, the arterial tree thickens and decreases in compliance, resulting in increased pulse wave velocity, systolic blood pressure, and left ventricular afterload. In response to these arterial changes, the myocardium remodels to maintain systolic function and diastolic filling. These adaptive mechanisms are not necessarily pathologic but increase the susceptibility for myocardial ischemia and heart failure in the presence of common age‐associated comorbidities. This article reviews the pathophysiology of cardiovascular aging and discusses therapeutic interventions that may ameliorate these processes.

Singam et al. (2019) conducted a review in Cardiovascular aging. Caloric restriction, exercise training, antioxidants was evaluated on Age-associated changes in cardiovascular structure and function (null, 95% CI null, p=null). Caloric restriction has been suggested to reduce the rate of biological aging, potentially improving cardiovascular outcomes in healthy nonobese adults aged 21-50 years.
