Hypertension affects over one billion people worldwide, with India bearing a significant burden due to its population, diversity, and demographics. In India, hypertension affects 21% of women and 24% of men, while pre-hypertension affects 39% of women and 49% of men. The prevalence of hypertension increases in the population with obesity. Even 7% of school-going children in India have hypertension, especially in urban and overweight children. However, awareness and control of hypertension in India are inadequate. Only 57% of women and 38% of men have been diagnosed with hypertension; among them, only a fraction receive appropriate medication. The overall control of hypertension stands at 15%, with regional variations. Hypertension significantly contributes to cardiovascular and renal diseases, and better detection and treatment could reduce their impact in India. At the total population level, reducing systolic blood pressure (SBP) by 2 mm Hg may significantly affect cardiovascular disease. Considering the unique challenges faced in India, the InSH stresses the importance of a tailored approach to hypertension management. They plan to disseminate guidelines through practitioner training and patient awareness campaigns. These guidelines will cover screening, diagnosis, management, handling hypertension with other conditions, long-term follow-up, and patient education. In conclusion, this position paper calls for immediate action to improve hypertension management in India and alleviate the associated disease burden and mortality.","PeriodicalId":16070,"journal":{"name":"Journal of Human Hypertension","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41371-024-00960-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142375558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identified studies reported PWV values in individuals with both favorable and unfavorable outcomes at the end of follow-up.

Microalbuminuria was defined as a urine albumin-to-creatinine ratio between 30 and 300 mg/g. Microvascular reactivity was evaluated using LSCI to perform noninvasive measurements of cutaneous microvascular perfusion changes. Pharmacological (acetylcholine [ACh], or sodium nitroprusside [SNP]) and physiological (postocclusive reactive hyperemia [PORH]) stimuli were used to evaluate vasodilatory responses. Thirty-two patients with RH and a normal urine albumin-to-creatinine ratio (RH group) and 32 patients with RH and microalbuminuria (RH + MAU) were evaluated.

In this study, we compared the WatchBP Office Central (a Type 2 central pressure estimation device) against a high-fidelity micromanometer in the ascending aorta of anaesthetised patients undergoing clinically-indicated catheterisation (<i>n</i> = 15, age 4–16 years). As a secondary aim, central systolic BP (cSBP) was also compared to two non-invasive estimation methods in 34 awake patients undergoing routine cardiac MRI (age 10–18 years). WatchBP substantially overestimated cSBP compared to the intra-arterial gold-standard reference (26.1 ± 7.4 mmHg), and recruitment was terminated at <i>n</i> = 11 (included in the analysis) due to high statistical certainty that the device would not pass the validation criteria of 5±8 mmHg. WatchBP cSBP was also substantially higher than values obtained from a phase contrast MRI method (11.8 ± 7.9 mmHg) and the SphygmoCor XCEL (13.5 ± 8.9 mmHg) in the awake patient group, which translate to 21–23 mmHg on average after accounting for known/estimated biases in these non-invasive comparators. Compared with invasive central diastolic and systolic BPs, the brachial measures from WatchBP yielded errors of 0.1 ± 5.6 and 12.5 ± 6.0 mmHg respectively.
