Impact of nutrition status on admission on the incidence of non-fetal cardiovascular events in super-elderly hypertensive patients

Objective To discuss the effect of nutritional status on admission on incidence of non fatal cardiovascular events within 90 d in super elderly patients with hypertension in hospital. Methods This is a cohort study. The patients aged over 80 with hypertension hospitalized in Chinese PLA General Hospital from Jan 2011 to Dec 2013 were chosen. According to the nutritional status on admission, patients were divided into four groups and the incidences of non-fatal cardiovascular events at 7 d (D7), 14 d (D14), 30 d (D30) and 90 d (D90) were recorded. Results Those patients scored high for controlling nutritional status (CONUT) which means worse nutritional status showed higher incidence of non-fetal cardionvascular events (χ²=97.448, P=0.0000). Logistic regression analysis showed that CONUT was independent risk factor of non-fatal cardiovascular events (OR=1.188, 95% CI:1.042-1.354, P=0.01). Conclusion In super elderly patients with hypertension, the nutritional status on admission is independent risk factor of non fatal cardiovascular events. Increased CONUT means worse nutritional status, which links to poor prognosis. The effective treatment of mulnutrition may reduce the unfavorable prognosis in the super-elderly hypertensive patients.
