Outdoor temperature, blood pressure, and cardiovascular disease mortality

Feb 17, 2015 12:00 AM

Blood pressure is a major cause of cardiovascular disease (CVD) and both may increase as outdoor temperatures fall. A recent CKB analysis published in the European Heart Journal investigates seasonal variation in blood pressure and CVD mortality among patients with prior-CVD.

The paper "Outdoor temperature, blood pressure, and cardiovascular disease mortality among 23 000 individuals with diagnosed cardiovascular diseases from China" looked at CKB participants across 10 study regions and used Cox regression to examine the association of usual SBP with subsequent CVD mortality. Published in the European Heart Journal, It showed that among adult Chinese with prior-CVD, there is both increased blood pressure and CVD mortality in winter. To help reduce the winter excess CVD mortality in high-risk individuals both careful monitoring and more aggressive blood pressure lowering treatment in the cold months are recommended.
