Mathematical Study
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).

This study provided 374,250 hypertension managed Koreans 75 ages or earlier (Fig. https://datingranking.net/japan-cupid-review/ 1), whose standard features by the benefit measure are shown during the Desk step 1. Throughout the mean realize-upwards of five.six ages, twenty eight,621 customers experienced ischemic stroke, 14,683 got MI, and you may 74,115 clients passed away. Basically, clients that have aerobic event incidence had large costs from CVD exposure factorspared so you can members no incidents, people with ischemic stroke and you may MI incidence had rather large baseline blood circulation pressure, was in fact more mature, expected to end up being men, be current smokers, end up being truly inactive, has diabetic issues, dyslipidemia, and you will persistent kidney disease. Alcohol based drinks displayed more trends to possess ischemic coronary attack and you can MI. Brand new zero experiences groups got high cost of intestinal being obese and you can being obese. Surprisingly, in relation to mortality, people who died have been less likely to want to has actually dyslipidemia.
Flowchart from cohort selection. A maximum of 374 250 victims was qualified to receive the latest cohort, and have been implemented getting MI, ischemic stroke, and all-produce dying until
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.
Threat rates (HR) having ischemic heart attack, myocardial infarction (MI), and you will death according to the systolic hypertension (SBP) and you can diastolic blood pressure (DBP) category. The information is actually modified to own many years, intercourse, body mass index (BMI), smoking/ drinking/exercise/money updates, plus the presence regarding all forms of diabetes mellitus (DM), dyslipidemia, and you may chronic kidney disease (CKD). The newest 95% count on (CI) intervals receive because vertical contours towards Days
In the SBP/DBP combination analysis, HRs stratified by SBP/DBP groups were calculated (Fig. 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.
