Why a small waist might save your life if you have a pacemaker
Association of waist circumference with long-term all-cause mortality and cardiac death in patients with a pacemaker: a retrospective study
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
If you have a pacemaker, having a smaller waist might mean you're much less likely to die from heart problems or anything else over the next few years.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies
Max 44Case Reports & Case Series
Max 30Expert Opinion & Narrative Reviews

Evidence Score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

An increase in waist circumference is quantitatively associated with increased all-cause mortality risk in adult humans.
Almost 4 out of 10 people with pacemakers have a large waist, and common heart meds like beta-blockers or statins don’t seem to reduce this obesity.
For people with pacemakers, how heavy they are (BMI) doesn’t predict death risk — but how much fat they carry around their waist does.
For pacemaker patients, how big their waist is matters more for survival than how well their heart pumps or how old they are.
Pacemaker patients with a small waist are far less likely to die — only about 1 in 25 die from any cause over 6 years, while nearly 1 in 5 with a large waist do.
