Objective To examine the relationship between brachial and central carotid pressures and target organ indices at baseline and their association with future mortality. Methods We examined, cross-sectionally and longitudinally, the relations of baseline systolic and pulse pressures in central (calibrated tonometric carotid pulse) and peripheral (brachial, mercury sphygmomanometer) arteries to baseline left ventricular mass, carotid intima-media thickness, estimated glomerular filtration rate, and 10-year all-cause and cardiovascular mortality in 1272 participants (47% women aged 30–79 years) from a community of homogeneous Chinese. Results Left ventricular mass was more strongly related to central and peripheral systolic pressures than pulse pressures. Intima-media thickness and glomerular filtration rate were more strongly related to central pressures than peripheral pressures. A total of 130 participants died, 37 from cardiovascular causes. In univariate analysis, all four blood pressure variables significantly predicted all-cause and cardiovascular mortality. Each blood pressure variable was entered into the multivariate models, both individually and jointly with another blood pressure variable. After adjustment for age, sex, heart rate, BMI, current smoking, glucose, ratio of total cholesterol to high-density lipoprotein cholesterol, carotid–femoral pulse wave velocity, left ventricular mass, intima-media thickness, and glomerular filtration rate, only central systolic pressure consistently and independently predicted cardiovascular mortality (hazards ratio, 1.30 per 10 mmHg). No significant sex interactions were observed in all analyses. Conclusion Systolic and pulse pressures relate differently to different target organs. Central systolic pressure is more valuable than other blood pressure variables in predicting cardiovascular mortality.

The value of increased arterial wave reflection, usually assessed by the transit time–dependent augmentation index and augmented pressure (Pa), in the prediction of cardiovascular events may have been underestimated. We investigated whether the transit time–independent measures of reflected wave magnitude predict cardiovascular outcomes independent of arterial stiffness indexed by carotid-femoral pulse wave velocity. A total of 1272 participants (47% women; mean age: 52±13 years; range: 30 to 79 years) from a community-based survey were studied. Carotid pressure waveforms derived by tonometry were decomposed into their forward wave amplitudes, backward wave amplitudes (Pb), and a reflection index (=[Pb/(forward wave amplitude+Pb)]), in addition to augmentation index, Pa, and reflected wave transit time. During a median follow-up of 15 years, 225 deaths occurred (17.6%), including 64 cardiovascular origins (5%). In univariate Cox proportional hazard regression analysis, pulse wave velocity, Pa, and Pb predicted all-cause and cardiovascular mortality in both men and women, whereas augmentation index, reflected wave transit time, and reflection index were predictive only in men. In multivariate analysis accounting for age, height, and heart rate, Pb predicted cardiovascular mortality in both men and women, whereas Pa was predictive only in men. Per 1-SD increment (6 mm Hg), Pb predicted 15-year cardiovascular mortality independent of brachial but not central pressure, pulse wave velocity, augmentation index, Pa, and conventional cardiovascular risk factors with hazard ratios of ≈1.60 (all P <0.05). In conclusion, Pb, a transit time–independent measure of reflected wave magnitude, predicted long-term cardiovascular mortality in men and women independent of arterial stiffness.

Insulin resistance (IR), a metabolic risk factor, is linked to the pathogenetic mechanism of primary hypertension. Detecting IR in the patients with hypertension will help to predict and stratify the added cardiovascular risk, institute appropriate IR management, and manage hypertension optimally. There are many methods for assessing IR, each with distinct advantages and disadvantages. The euglycemic insulin clamp and intravenous glucose tolerance test, gold standards for measuring IR, are used in research but not in clinical practice. Homeostatic model assessment (HOMA‐IR), a method for assessing β‐cell function and IR, is frequently applied presently, particularly in Asia. Besides, the triglyceride–glucose index (TyG) first published by South American authors showed a good correlation with the insulin clamp technique and HOMA‐IR index. This simple, convenient, and low‐cost TyG index is of research interest in many countries in Asia and can be used to screen for IR in the Asian hypertensive community.

Stroke is the primary cause of disability and vascular death worldwide, including Asia. Asian characteristics that differ from the West lead to higher stroke incidence. Stroke epidemiology studies in Asia have shown varying levels of mortality, incidence, prevalence, and burden of disease. Hypertension is the most prevalent risk factor found in Asia. Besides ethnicity that is associated with stroke incidence, both systolic blood pressure, diastolic blood pressure, and blood pressure variability are positively correlated with stroke incidence. Post‐stroke cognitive impairment is one of the sequelae that affect one‐third of stroke survivors and has become a significant public health concern that is often neglected despite its increasing prevalence. Therefore, it is very important to prevent recurrence by treating stroke optimally and effectively. Increasing awareness and treatment adherence to hypertension, the leading risk factor for stroke, became the main goal in several countries in Asia.
