In CHD, Mental and Physical Health Status Both Impact Mortality Risk

Mental and physical health are both tied to the risk of mortality in patients with coronary heart disease (CHD), according to a recent study.

For their study, the researchers assessed 762 individuals with CHD (mean age 67.6 years) from 2004 to 2010.

Data were collected from each patient regarding patient-rated physical component summary (PCS) and mental component summary (MCS) scores of health status (from the 12-Item Short-Form Health Survey [SF-12]), demographics and clinical parameters at baseline, and all-cause mortality at 6-year follow-up.

Generalized estimating equations with a log-link function were used to conduct multivariate regression.

Results showed that the mean baseline SF-12 mental component (MCS) score was 50.0, and the corresponding mean physical component score (PCS) was 39.6. Adjusted odds ratios for baseline MCS and PCS for mortality were both 0.97.

Notably, the researchers observed a 14% decrease in the likelihood of all-cause mortality for every 5-point increase in MCS and PCS scores.

“Overall, the magnitude of effect for both mental health status and physical health status was similar; higher scores were significantly associated with a lower risk of mortality at 6-year follow-up,” the researchers concluded.
