This systematic review and meta-analysis compared lifestyle interventions with pharmacologic therapy for cardiovascular prevention in middle-aged and older adults. It included 21 randomized controlled trials and 11 prospective cohort studies, totaling 312 645 participants. In pooled analyses, lifestyle interventions were associated with lower risks of major adverse cardiovascular events (risk ratio: 0.85), all-cause mortality (0.88), cardiovascular mortality (0.84), and stroke (0.82). Combined diet and exercise programs had the greatest reported benefit (risk ratio: 0.80). The authors concluded that lifestyle modification offers cardiovascular protection comparable to or greater than pharmacologic therapy.
Key findings
- Lifestyle interventions reduced major adverse cardiovascular events (risk ratio: 0.85).
- Pooled risk ratios were 0.88 for all-cause mortality, 0.84 for cardiovascular mortality, and 0.82 for stroke.
- Combined diet and exercise programs showed the greatest benefit (risk ratio: 0.80).
Why it matters
The findings underscore the potential contribution of structured lifestyle modification to cardiovascular prevention across several clinically important outcomes. They also suggest that diet and exercise together may be more beneficial than other lifestyle approaches. Because the evidence combines randomized trials and prospective cohorts, the results support considering behavioral and pharmacologic strategies as complementary rather than assuming one replaces the other.
What to keep in mind
The evidence combines randomized trials with prospective cohort studies, which differ in design and may not support equally strong causal conclusions.
