Statistical Analysis
Baseline characteristics are presented as means with standard deviation for continuous variables and numbers and percentages for categorical variables. Annual incidence rates (IR) were calculated as the number of events per 1000 person-years. Cox proportional hazard models were used to estimate HR and 95 % confidence intervals (CI) to analyze association between baseline blood pressure subgroups and cardiovascular and mortality outcomes. Additional analysis according to SBP/DBP combination groups was performed. Two-tailed P-values < 0.05 were considered statistically significant. Statistical analyses were conducted using SAS version 9.4 (SAS Institute Inc, Cary, NC, USA).
Performance
This study included 374,250 hypertension managed Koreans 75 years otherwise more mature (Fig. 1), whoever baseline functions because of the lead scale get in Table 1. During the imply pursue-upwards of 5.6 many years, twenty eight,621 patients educated ischemic coronary arrest, 14,683 had MI, and 74,115 patients passed away. Essentially, clients which have aerobic knowledge frequency had large costs regarding CVD chance factorspared to players no occurrences, those with ischemic coronary attack and MI chance got rather large baseline blood pressure level, was in fact more mature, likely to end up being men, feel latest smokers, be personally deceased, has actually diabetes, dyslipidemia, and you may persistent kidney problem. Alcohol based drinks displayed other fashion to have ischemic heart attack and you will MI. Brand new no enjoy organizations had large prices regarding intestinal obesity and obesity. Remarkably, in relation to death, those who passed away was indeed less inclined to has dyslipidemia.

Cox regression analysis of adjusted HRs by SBP and DBP are shown in Fig. 2. The reference groups were SBP 120 to 129 mmHg and DBP < 70 mmHg. All three outcomes measures showed highest HRs and IRs with SBP ? 170 mmHg or DBP ? 100 mmHg, except for all-cause death with highest risk when SBP < 110 mmHg. HR by SBP followed a J-curve pattern for ischemic stroke, and a U-shaped pattern for all-cause death. The nadir SBP ranges were 120 to 129 mmHg (HR 1, reference group) and 140 to 149 mmHg (HR 0.961; 95 % CI 0.937 to 0.985) for ischemic stroke and all-cause death, respectively. For MI, SBP < 160 mmHg was a relatively homogenous group and HR significantly increased only once SBP ? 160 mmHg. Meanwhile, increasing DBP generally showed higher HRs for ischemic stroke. For MI and all-cause death, DBP up to 80 mmHg and 90 mmHg did not show any significant differences from the reference group, and HR significantly increased when DBP was ? 80 mmHg or ? 90 mmHg, respectively.
Danger rates (HR) to possess ischemic stroke, myocardial infarction (MI), and death according to the systolic blood pressure levels (SBP) and you may diastolic blood pressure level (DBP) class. The information and knowledge are modified for years, intercourse, bmi (BMI), smoking/ drinking/exercise/earnings condition, plus the presence out-of diabetic issues mellitus (DM), dyslipidemia, and you may persistent kidney condition (CKD).

In the SBP/DBP combination analysis, HRs stratified by SBP/DBP groups were calculated (Fig www.datingranking.net/dating4disabled-review. 3). The reference group was SBP 130 to 149 mmHg/DBP < 80 mmHg. For each SBP group, higher DBP groups yielded higher HRs for all three outcomes, except when SBP ? 150 mmHg, DBP < 80 mmHg had higher HRs than when DBP was 80 to 89 mmHg, also for all three outcomes. Regardless of SBP control, patients with the highest DBPs ? 90 mmHg had higher HRs compared to the reference group. While there was no additional consistent trend in ischemic stroke and MI, in terms of all-cause death, within the same DBP group, the highest HRs lay in the SBP groups < 130 mmHg.
