ABSTRACT
Introduction: Hypertension is the most prominent established risk factor for adverse cardiovascular outcomes. The influence of hypertension in combination with other major cardiovascular disease risk factors (CVD-RFs) on mortality and cardiovascular events has not been fully comprehended yet due to their overlapping and interconnected nature. This study was conducted to evaluate the impact of CVD-RFs quantity on the occurrence of cardiovascular events, CVD-related mortality, and all-cause mortality rates in hypertensive patients. Design and Method: In a secondary analysis of the Isfahan Cohort Study, demographic information, anthropometric measures, and laboratory results of participants were extracted. During the 15 years of follow-up, all-cause mortality, CVD-related mortality, and the occurrence of nonfatal cardiovascular events were assessed by separate panels of experts. Data analysis was performed using Cox proportional hazard models to estimate adjusted hazard ratios (HRs) among normotensive and hypertensive individuals in two subgroups of 3 CVD-RFs and≥ 3 CVD-RFs. Results: Among 5432 eligible participants, hypertensive patients (n = 1509) had 1.3, 2, and 1.4 times higher HRs for all-cause mortality, CVD-related mortality, and nonfatal cardiovascular events, respectively. Compared to the normotensives, HRs for the mentioned outcomes were 1.2, 1.7, and 1.3 for hypertensive participants with < 3 CVD-RFs and 1.7, 3.4, and 2.3 for hypertensive participants with≥ 3 CVD-RFs. These rises were shown to be highly significant (p = 0.003, p = 0.001) for CVD-related mortality and nonfatal cardiovascular events in hypertensives with ≥ 3 CVD-RFs compared with hypertensives with < 3 CVD-RFs. Conclusions: Hypertension alone or combined with other CVD-RFs increases the chance of all-cause mortality, CVD-related mortality, and nonfatal cardiovascular events. Rises in the quantity of other CVD-RFs (specifically to≥ 3) result in highly significant increases in fatal and nonfatal cardiovascular events. Therefore, to reduce mortality and cardiovascular events, hypertensive patients should be thoroughly evaluated for coexisting CVD-RFs, aiming to limit the synergistic effects of multiple CVD-RFs by properly managing modifiable RFs.
