Even though it has been more than a decade since renal denervation (RDN) was first used to treat hypertension and an intense effort on researching this therapy has been made, it is still not clear how RDN fits into the antihypertensive arsenal. There is no question that RDN lowers blood pressure (BP), it does so to an extent at best corresponding to one antihypertensive drug. The procedure has an excellent safety record. However, it remains clinically impossible to predict whose BP responds to RDN and whose does not. Long-term efficacy data on BP reduction are still unconvincing despite the recent results in the SPYRAL HTN-ON MED trial; experimental studies indicate that reinnervation is occurring after RDN. Although BP is an acceptable surrogate endpoint, there is complete lack of outcome data with RDN. Clear indications for RDN are lacking although patients with resistant hypertension, those with documented increase in activity of the sympathetic system and perhaps those who desire to take fewest medication may be considered. ispartof: JOURNAL OF HYPERTENSION vol:40 issue:10 pages:1859-1875 ispartof: location:Netherlands status: published

The prevalence of hypertension and comorbidities such as metabolic syndrome, diabetes mellitus, and chronic kidney disease in India is alarmingly high. Amlodipine, an older-generation calcium channel blocker (CCB), is currently the gold standard for hypertension management in India. However, it has several disadvantages, including reflex tachycardia and pedal edema. Therefore, an effective antihypertensive agent that does not cause these adverse effects and provides end-organ protection is required for the holistic management of hypertension in the country. Azelnidipine is a new-generation CCB that has recently been approved for the treatment of hypertension in India. This review provides an overview of the utility of azelnidipine for hypertension control, including comparisons with traditional CCBs such as amlodipine. It discusses the key antihypertensive effects of azelnidipine as well as its advantages in the prevention of tachycardia and associated complications. In addition, this review highlights the extensive cardio- and renoprotective activities of azelnidipine, including its effects on systolic and diastolic function and urinary albumin excretion. Overall, this substantial body of evidence supports the use of azelnidipine for the treatment of hypertension, especially in India. It suggests that the adoption of azelnidipine as the new gold standard CCB could help India battle its hypertension epidemic.

Aims The effect of the COVID-19 pandemic on care and outcomes across non-COVID-19 cardiovascular (CV) diseases is unknown. A systematic review and meta-analysis was performed to quantify the effect and investigate for variation by CV disease, geographic region, country income classification and the time course of the pandemic. Methods and results From January 2019 to December 2021, Medline and Embase databases were searched for observational studies comparing a pandemic and pre-pandemic period with relation to CV disease hospitalisations, diagnostic and interventional procedures, outpatient consultations, and mortality. Observational data were synthesised by incidence rate ratios (IRR) and risk ratios (RR) for binary outcomes and weighted mean differences for continuous outcomes with 95% confidence intervals. The study was registered with PROSPERO (CRD42021265930). A total of 158 studies, covering 49 countries and 6 continents, were used for quantitative synthesis. Most studies (80%) reported information for high-income countries (HICs). Across all CV disease and geographies there were fewer hospitalisations, diagnostic and interventional procedures, and outpatient consultations during the pandemic. By meta-regression, in low-middle income countries (LMICs) compared to HICs the decline in ST-segment elevation myocardial infarction (STEMI) hospitalisations (RR 0.79, 95% confidence interval [CI] 0.66–0.94) and revascularisation (RR 0.73, 95% CI 0.62–0.87) was more severe. In LMICs, but not HICs, in-hospital mortality increased for STEMI (RR 1.22, 95% CI 1.10–1.37) and heart failure (RR 1.08, 95% CI 1.04–1.12). The magnitude of decline in hospitalisations for CV diseases did not differ between the first and second wave. Conclusions There was substantial global collateral CV damage during the COVID-19 pandemic with disparity in severity by country income classification.

Introduction: Hypertension is highly prevalent in patients with type II diabetes mellitus. India has some of the highest rates of diabetes and hypertension worldwide, but there is a lack of local data on the coexistence of these two risk factors. This study determined the prevalence of hypertension in patients with, or at high risk of, type II diabetes mellitus from across India. Methods: Data came from a nationwide trial evaluating the effects of yoga-based lifestyle modification for the prevention/management of type II diabetes. Participants were recruited based on randomized house-to-house screening in urban and rural areas from 65 districts of 29 states/union territories. Eligible individuals were aged 20–80 years and had diabetes or were at high risk of diabetes (IDRS ≥ 60). Anthropometric and demographic data were obtained, and resting blood pressure and blood glucose levels were recorded. Results: This analysis included data from 14,135 individuals. Of these, 25% had self-reported diabetes, 19% were diagnosed with diabetes during the trial, and 26.8% were at high risk for type II diabetes. In these three patient groups, hypertension prevalence rates were 58%, 41.0%, and 35.8%, respectively. The prevalence of hypertension was highest in the North East region and lowest in the North West. Conclusion: The high prevalence of hypertension in patients with, or at risk of diabetes, highlights the urgent need for policies to manage this population, who are at high risk of cardiovascular disease and death.

About 1/4th of adults have high blood pressure which is the single most important risk for death (including heart disease and stroke).There are effective policies that could facilitate people making healthy choices to prevent raised blood pressure, and if fully implemented, could largely prevent hypertension from occurring.Hypertension is easy to screen and treat for BUT only about 50% of adults with hypertension are aware of their condition and only about 1 in 7 is adequately treated.Preventing and controlling high blood pressure is the major mechanism for NCD prevention and control and a model for other NCD risks.Effective lifestyle and drug treatments could prevent and control hypertension in most individuals if systematically applied to the population, simple interventions are feasible in all settings, and can be used to enhance primary care.Urgent sustained action is needed is needed for effective public policies and health system changes to prevent and control hypertension.Cerca de una cuarta parte de los adultos tienen hipertensión, el principal factor de riesgo de muerte (inclusive la causada por cardiopatía y accidente cerebrovascular).Existen políticas eficaces que podrían ayudar a las personas a elegir opciones saludables para prevenir el aumento de la presión arterial; si se las aplicara plenamente, se podría evitar en gran medida el desarrollo de hipertensión.La hipertensión es fácil de detectar y tratar, PERO solo alrededor de 50% de los adultos que presentan dicha afección son conscientes de su situación y solamente 1 de cada 7 de ellos recibe el tratamiento adecuado.La prevención y el control de la hipertensión es el mecanismo principal para prevenir y controlar las enfermedades no transmisibles y un modelo para evitar otros riesgos de presentar dichas enfermedades.La adopción de un modo de vida saludable y el tratamiento farmacológico efectivo podrían prevenir y controlar la hipertensión en la mayoría de las personas si se implementaran de manera sistemática en la población; en todos los entornos es posible aplicar intervenciones sencillas, que pueden usarse para mejorar la atención primaria.Es urgente adoptar medidas sostenidas para introducir cambios eficaces en las políticas públicas y los sistemas de salud pública con miras a prevenir y controlar la hipertensión.

The coronavirus disease-2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 that has significant implications for the cardiovascular (CV) health of patients, although the respiratory disease is the predominant clinical sign of COVID-19. The presence of comorbidities such as hypertension, diabetes, and CV disease (CVD) increases the risk of morbidity and mortality due to CVD. Numerous patients with COVID-19 have basic CV ailments or develop severe heart injury due to the disease. Severe CV injury characterized by a huge rise of heart troponins is the most commonly seen effect on the heart. This happens in approximately 8%–12% of all patients. Direct myocardial injury because of viral association of cardiomyocytes and the effect of systemic inflammation appear to be the most common mechanisms responsible for the cardiac injury. The presence of preexisting CV disease and/or development of acute cardiac injury is associated with significantly worse outcomes in patients with COVID-19. Most of the current reports on COVID-19 have only briefly described CV manifestations in these patients. Given the significant adverse prognostic impact of cardiac involvement, further studies are needed on the incidence, mechanisms, clinical presentation, and outcomes of various CV manifestations in patients with COVID-19.

Uncontrolled hypertension is an important cardiovascular risk factor and therefore requires effective approaches to patient management. This study assessed approaches to the management of patients with Stage 2 hypertension by cardiologists in India. This was a retrospective, multicenter, observational, case-based questionnaire study. Data on demographic characteristics, risk factors associated with Stage 2 hypertension, use of antihypertensive medications, side effects, and approaches to education for 2,540 patients were extracted from questionnaire responses provided by 508 cardiologists. The study population of patients with Stage 2 hypertension had a mean age of 55.0 years. Most of the patients (62.6%) were aged 30 to 60 years and diabetes mellitus was the most prevalent comorbidity (48.9%). Triple antihypertensive therapy was being used by 760 patients, and 634 and 1,146 patients were receiving 4 and 5 different antihypertensive medications, respectively. Telmisartan, amlodipine, chlorthalidone, hydrochlorothiazide, spironolactone, metoprolol, and prazosin were the commonly prescribed drugs. Ankle edema (27.7%) was the most frequent side effect of therapy. Pharmacotherapy was supported by patient education and lifestyle modifications for better blood pressure control. The standardized approach to the collection and assessment of these contemporary data provides useful insights into the characteristics and treatment of patients with Stage 2 hypertension in India.

BACKGROUND Stroke is an important neurological disorder with significant morbidity and mortality. In India, the risk factors for stroke (obesity, diabetes mellitus, alcoholism, hypertension, and sedentary lifestyle) are mounting with economic growth and increasing the disease burden. OBJECTIVE To assess the severity and risk factors of stroke in India and identify any new predisposing factors. METHODS A multicentric (six tertiary care hospitals across India) prospective observational study (from September 2016 to July 2017) was conducted on 526 stroke patients, presenting within the first 24 h to examine the risk factors for ischemic and hemorrhagic strokes. Severity was determined using the National Institutes of Health Stroke Scale (NIHSS). RESULTS Predominantly male (72.3%), 75% of the sample was >50 years old, with a mean body mass index (BMI) of 25.8 ± 4.3 kg/m2 and 14.6% obese patients. Hypertension and diabetes mellitus were the commonest comorbidities, followed by a history of ischemic heart disease and familial history of stroke. 20.5% of patients had mild strokes, 57.4% had moderate, 8.4% experienced moderate-severe strokes, whereas 7.2% had severe strokes. Regarding the admission diagnoses, 56.8% were ischemic, 18.6% were hemorrhagic, 1.1% had a transient ischemic attack, 6.6% suffered recurrent strokes, and 17% were other forms. CONCLUSION The foremost risk factors for stroke in India, hypertension and diabetes, need to be controlled and treated like other global high-risk populations for stroke prevention. The NIHSS scores highlight the relationship between risk factors and stroke severity.

Purpose of review Hypertension is the most important noncommunicable disease risk factor in India with an estimated burden of 200 million persons. Nationwide studies and meta-analyses have reported increasing prevalence. We summarize unique features of hypertension in India. Recent findings Two recent nationwide studies to determine hypertension prevalence have been performed-Fourth National Family Health Survey and Fourth District Level Health Survey/Annual Health Survey. Age-adjusted hypertension was more in men (24.5%) than women (20.0%). Hypertension is more common in developed states of the country, urban populations and better socioeconomic status individuals. Urban-rural convergence and greater hypertension in younger men and women are unique findings. There is low status of its awareness, treatment and control. Diabetes prevalence is high in hypertension suggesting importance of insulin resistance. Prevalence of resistant hypertension is high. Pharmacoepidemiology studies have reported widespread use of all classes of antihypertensive drugs with increasing use of renin-angiotensin system blockers. There are limited studies focused on genetic epidemiology. Summary Hypertension is widely prevalent in India with large regional variation, greater prevalence in urban areas and the young. Treatment and control status are low. Diabetes is important comorbidity and resistant hypertension is frequent. There is widespread use of newer antihypertensive drugs.

Background: Isolated diastolic hypertension (IDH) has been actively discussed for the last two decades because of its prevalence in a younger population and its association with cardiovascular disease. Furthermore, the association of IDH is significant in South Asian Countries such as India because relatively younger populations are known to have a higher risk of cardiovascular events. Objective: The objective of this study is to find prevalence of IDH and its risk correlates in a semiurban population of South Indian state of Andhra Pradesh. Methods: Data were collected using the modified World Health Organization - STEPwise approach to Surveillance (WHO STEPS) questionnaire for 16,636 individuals from a group of villages under Thavanampalle Mandal. Collated data were analyzed for prevalence and risk factors of IDH. Results: Prevalence of IDH was found to be 4.0% with mean age of 46.0 (±SD 13.6) years and a relatively higher prevalence in men (5.3%) as compared with women (3.2%). The prevalence of IDH peaked in the fifth decade of life (40–49 years of age) and declined thereafter. Among various risk factors that were analyzed for their association with IDH, only age, body weight, and body mass index retained their significance in multivariate binary logistic regression analysis. Conclusion: There is a significant prevalence of IDH below 50 years of age in the semiurban population of South India. As IDH in young and middle age is known to be associated with increased risk of cardiovascular events and end organ involvement, it highlights need for study and development of effective IDH management strategies to reduce associated morbidity and mortality.

Background The current gold standard for blood pressure (BP) measurements is based on office BP measurements (OBPMs) by a sphygmomanometer or a digital device. Ambulatory BP measurement (ABPM) is a noninvasive method for continuous monitoring of BP over a period during routine activities of the patient. Thus, ABPM offers multiple BP readings during the patients’ daily routine as compared to the single reading by OBPM at rest. A good correlation exists between mean 24-hour BP readings and the prediction of cardiovascular events. The present multicenter observational study was aimed to assess the correlation between ABPM and OBPM in patients with newly diagnosed, controlled, or uncontrolled hypertension in the community setting. Our hypothesis was to test if ABPM provides any further value in those hypertensive patients in whom the office blood pressure levels are controlled. A supplementary hypothesis was whether obtaining ABPM in patients with newly diagnosed or uncontrolled hypertension yields any value over and beyond OBPM. Another objective was to find out the applicability of ABPM in the community setting where the medical care is provided by primary care family physicians and not by specialists. Materials and Methods A total of 1000 patients were analysed for this study. Those with controlled hypertension were assigned to Group A, and those with newly diagnosed/untreated hypertension comprised Group B. Group A was followed up during Visit 2 and Group B was followed up during Visit 2 and either Visit 3 or Visit 4 to assess the BP measurements by ABPM and OBPM. Results The correlation between ABPM and OBPM showed minimal variation in the BP readings of Group A subjects at Visit 2. A variation in BP readings was observed in Group B at Visit 2. Furthermore, the correlation was established between ABPM and OBPM noted for Group B subjects during Visit 3, and minimal variation was noted during Visit 4. Conclusions A good correlation was observed between ABPM and OBPM during both visits in patients in Groups A and B. However, a notable variation was noted in the diastolic BP readings. Thus, large-scale clinical studies are required to detect the prevalence of hypertension, masked hypertension, and dipping patterns associated with hypertension and other related medical co-morbidities.

The SARS-CoV-2 virus spreading across the world has led to surges of COVID-19 illness, hospitalizations, and death. The complex and multifaceted pathophysiology of life-threatening COVID-19 illness including viral mediated organ damage, cytokine storm, and thrombosis warrants early interventions to address all components of the devastating illness. In countries where therapeutic nihilism is prevalent, patients endure escalating symptoms and without early treatment can succumb to delayed in-hospital care and death. Prompt early initiation of sequenced multidrug therapy (SMDT) is a widely and currently available solution to stem the tide of hospitalizations and death. A multipronged therapeutic approach includes 1) adjuvant nutraceuticals, 2) combination intracellular anti-infective therapy, 3) inhaled/oral corticosteroids, 4) antiplatelet agents/anticoagulants, 5) supportive care including supplemental oxygen, monitoring, and telemedicine. Randomized trials of individual, novel oral therapies have not delivered tools for physicians to combat the pandemic in practice. No single therapeutic option thus far has been entirely effective and therefore a combination is required at this time. An urgent immediate pivot from single drug to SMDT regimens should be employed as a critical strategy to deal with the large numbers of acute COVID-19 patients with the aim of reducing the intensity and duration of symptoms and avoiding hospitalization and death.

While elevated blood pressure is a recognized risk factor for cardiovascular disease, the prevalence of hypertension still remains unclear for most populations. A door-to-door survey was conducted using modified WHO STEPS questionnaire in a group of villages under the Thavanampalle Mandal of Chittoor District in the state of Andhra Pradesh of South India. Data were collated and analyzed for 16,636 individuals (62.3% females and 37.7% males) above 15 years of age. Overall, prevalence of hypertension (as per JNC-7 classification) was found to be 27.0% (95% CI, 26.3, 27.7) in the surveyed community with 56.7% of the total hypertensives being diagnosed for the first time during the survey. An additional 39.1% had their blood pressure readings in the prehypertensive range. Among the known Hypertensives on treatment only 46.2% had a blood pressure recording within acceptable limits, with 31.2% in the prehypertensive range and only 15.0% in the normal range. Systolic blood pressure (SBP) of the surveyed population showed a continuous linear increase with age, but diastolic blood pressure (DBP) peaked and started reducing in early fifth decade in males. Male gender, increasing age, higher body mass index (BMI), increased waist-hip ratio, increased body weight, family history of hypertension, death of spouse, and diabetes were found to be positively correlated with hypertension. Risk factors of alcohol intake, use of ground nut/palm oil, and family history of diabetes lost their independent predictive ability for hypertension on multivariate logistic regression analysis. The level of physical activity was also not found to be a significant predictor of hypertension in the study population.
