Overview

May inform timing of prevention in high-risk patients; hypothesis-generating and requires prospective validation.

Structured PICO

P
Population
86 elderly subjects, retired, living closely-supervised in a home for the aged
O
Outcome
Time of occurrence of cardiac death due to arrhythmia, heart failure, or acute myocardial infarctionhard clinical

Cardiac mortality exhibits circadian, weekly, and seasonal variations, suggesting time-dependent risk states that could inform preventive strategies.
