Systemic vascular disease is a major public health issue all over the world. Vascular disease causes significant morbidity and excessive mortality. Risk factors for vascular disease like hypertension, diabetes, hyperlipidemia, and tobacco consumption inflict vascular disease by causing endothelial dysfunction. Endothelium, the innermost layer of the blood vessels governs vascular tone and vasomotion. Abnormal endothelial function promotes vasoconstriction and atherothrombosis. Thus, endothelial dysfunction predisposes to vascular disease affecting target organs --- brain, heart, and the kidneys, etc. Endothelial dysfunction, thus, is a precursor in the onset and progression of systemic vascular disease and atherosclerosis. Future interventions to prevent vascular disease should include modalities to preserve endothelial function and to reverse endothelial dysfunction. Endothelial function is critical to maintain holistic public health.

Hypertension is one of the leading causes of cardiovascular disease-related morbidity and mortality globally. Over the last several decades, there has been a broad shift in the management and pharmacologic treatment, specifically of hypertension, from a step-care approach to an individualized approach, and now to a population-based approach to increase the control rate of hypertension with the overall goal of decreasing major cardiovascular events related to poor control of hypertension. The Global HEARTS initiative of the World Health Organization and the HEARTS in the Americas Program of the Pan American Health Organization, in addition to the efforts of other organizations, serve as a blueprint for the implementation of a standardized, population-based approach to treating hypertension in the primary health-care setting. We have implemented components of such a program in our primary care clinic and resistant hypertension clinic here in Columbia, South Carolina, U.S. While the U.S. is a high-income country, the demographics of our clinic is one of low income and health literacy and our population is primarily black and Hispanic, female, and of an older age. Our clinic has successfully applied population-based treatment principles on an individualized basis to improve hypertension control rates and cardiovascular disease in our local community.

Heart rate, sympathetic nervous system, and renin-angiotensin-aldosterone system activity also decline. However, with time, substantial weight is typically regained in most individuals who lose weight, and the beneficial effects of weight loss on BP decline or are reversed. The initial decline in BP with weight loss is likely enhanced by negative caloric balance. Thus, even with isocaloric weight loss maintenance, the magnitude of the initial BP reduction appears to decline with time. Of further concern, the complex physiological (counterregulatory) adaptations to weight loss foster weight regain as more calories are desired than required and energy expenditure falls. Sustained weight loss generally requires a substantial long-term time commitment to physical activity and a high level of vigilance. High protein, low glycemic, high fiber, and reduced energy density diets may also be beneficial in reducing hunger and increasing satiety. Individuals who are counseled to lose weight should be aware of the challenges in maintaining weight loss, receive education on the lifestyle changes required to sustain weight loss, and commit to an evidence-based plan designed to foster long-term success. Future research directed at blocking or ameliorating the disproportionately large reductions of anorexigenic hormones and decreases in energy expenditure that accompany weight loss would help sustain the beneficial effects of weight loss on BP.

The remarkable reductions in cardiovascular events and the blunting of the decline in kidney function observed in clinical trials of patients with diabetes, cardiovascular disease, and/or chronic kidney disease treated with sodium-glucose co-transporter 2 (SGLT2) inhibitors are accompanied by a modest reduction in systolic (2–5 mm Hg) and diastolic (0.5–2.5 mm Hg) blood pressure. Blood pressure reduction occurs across a spectrum of blood pressure elevations, possibly including those with resistant hypertension, many of whom are already taking a variety of antihypertensive drugs. SGLT2 inhibitors appear to lower blood pressure to a greater extent in hypertensive Black and Asian individuals than White individuals. Mechanisms by which SGLT2 inhibitors likely contribute to blood pressure reduction and other cardiovascular and kidney benefits involve a variety of neuroendocrine, kidney, and hemodynamic systems. Some of these components include osmotic diuresis and natriuresis with a consequent decline in both interstitial and intravascular volume, weight reduction, a reduction in arterial stiffness, cardiac ventricular remodeling, loss of salt sensitivity, a decrease in uric acid concentrations, and a complicated interaction with the renin-angiotensin-aldosterone and sympathetic nervous systems. This review will provide an update on mechanisms purported to contribute to blood pressure reduction and the cardiovascular and kidney benefits observed with this the class of agents.

studies have shown a continuous association between elevated blood pressure (BP) and incident coronary heart disease (CHD), stroke, heart failure (HF), and vascular mortality, with the association noted from BPs above 115/75 mmHg. [4] Meta-analyses of randomized controlled trial (RCTs) including several hundred thousand patients have shown that a 10-mmHg reduction in systolic BP (SBP) or a 5-mmHg reduction in diastolic BP (DBP) is associated with significant reductions of ~ 20% for all major CV events, 10–15% for all-cause mortality, ~ 35% for stroke, ~ 20% for coronary events, and ~ 40% for HF. [3,5] In guidelines recommend BP thresholds to simplify the diagnosis of and guide treatment decisions in the management of hypertension.

However, intensive BP therapy comes with a higher risk of side effects. It is, therefore, important to identify individuals with higher cardiovascular risk who will in turn derive the greatest absolute benefit from BP reduction. In line with this, both ACC/AHA and European guidelines on the management of hypertension recommend the use of risk assessment using traditional risk factors. The European guidelines also recommend complementing risk estimation using additional markers of hypertension-mediated organ damage. Cardiac biomarkers such as natriuretic peptide and high sensitivity cardiac troponins (hs-cTn) reflect structural and/or functional changes in end organs (i.e., myocardium, vasculature) and have been associated with increased cardiovascular risk. These cardiac biomarkers may supplement risk assessment of patients with elevated BP and help personalize treatment strategies. Both NT-pro B type Natriuretic Peptide (NT-proBNP) and hs-cTn have been shown to predict cardiovascular events across different systolic and diastolic BP categories. Furthermore, observational data suggest that individuals with elevated levels of NT-proBNP and/or high-sensitivity troponin have lower numbers needed to treat to prevent cardiovascular events with intensive BP therapy, with the lowest NNT seen in those with elevated levels of both. While the data related to biomarkers in hypertension are encouraging, future randomized clinical trials are needed to further characterize the clinical utility of biomarker-based evaluation and treatment strategies in patients with hypertension.

Prediction models also known as clinical prediction models are mathematical formula or equation that expresses the relationship between multiple variables and helps predict the future of an outcome using specific values of certain variables. Prediction models are extensively used in numerous areas including clinical settings and their application is large.[1] In clinical application, a prediction model helps to detect or screen high-risk subjects for asymptomatic disease for early interventions, predict a future disease to facilitate patient-doctor communication based on more objective information, assist in medical decision-making to help both doctors and patients to make an informed choice regarding the treatment, and assist in health-care services with planning and quality management.[1,2] For example, there exist many prediction models for calculating the risk of developing hypertension in the future.[3-5] While specific details may vary between prediction models, the goal and process of developing prediction models are mostly similar. Conventionally, a single prediction model is built from a dataset of individuals in whom the outcomes are known and then the developed model is applied to predict outcomes for future individuals. There are two main components of prediction modeling: model development and model validation. Once a model is developed using an appropriate modeling strategy, its utility is assessed through model validation. Investigators want to see through validation how the developed model works in a dataset that was not used to develop the model to ensure that the model’s performance is adequate for the intended purpose.
