What is the characterisation of hypertension?
Best insight from top research papers
Hypertension, also known as high blood pressure, is characterized by persistent elevated blood pressure in systemic arteries . It is a haemodynamic disorder marked by increased peripheral vascular resistance, leading to severe complications like myocardial infarction, renal failure, strokes, and even death if left untreated . Hypertensive heart disease, a consequence of hypertension, involves changes in the myocardium and is associated with sudden cardiac death, often without prior symptoms, making clinical risk stratification challenging . Hypertension is a major risk factor for various conditions like stroke, heart failure, and chronic obstructive pulmonary disease, with primary hypertension accounting for a majority of cases . Cardiovascular magnetic resonance studies have shown that hypertension is linked to concentric left ventricular hypertrophy, reduced left ventricular function, and adverse cardiovascular remodeling, emphasizing the importance of effective blood pressure control in preventing complications .

What is hypertension explain?5 answersHypertension, commonly known as high blood pressure, is a prevalent global health issue associated with increased cardiovascular disease risk. Initially described in the 1800s, hypertension involves elevated blood pressure levels, leading to complications like left ventricular hypertrophy and renal damage. The condition is categorized into stages based on blood pressure measurements, with persistent elevation causing organ damage over time. Hypertension's pathophysiology is complex, involving genetic and environmental factors that affect cardiac output and vascular resistance. While hypertension prevalence rises with age, effective management through medications and lifestyle modifications is crucial to prevent associated risks like cognitive decline and cardiovascular events. Treatment guidelines recommend individualized approaches considering patient values and clinical judgment, especially in older adults with cognitive impairment or poor functional status.
What are hypertension clasification?4 answersHypertension classification involves various approaches based on different aspects. Bright's work in 1827 initiated the understanding of renal hypertension. Aoki proposed a three-way classification in 1985, categorizing hypertension into gene, environment, and disease hypertension. Giles et al. emphasized the importance of incorporating cardiovascular risk factors and early disease markers into hypertension classification, suggesting a continuum-based approach. Burtnett et al. described clinical classes of hypertensive disorders in pregnancy, including chronic hypertension, gestational hypertension, and preeclampsia. Fajar et al. utilized the LVQ algorithm for hypertension classification, achieving an average accuracy of 94% in detecting hypertension. These classifications consider genetic, environmental, cardiovascular risk factors, and pregnancy-related aspects to better understand and manage hypertension.
What is the definition of hypertension?5 answersHypertension, also known as elevated blood pressure, is a condition characterized by persistently raised pressure in the arterial blood vessels, leading to increased stress on the cardiovascular system. This condition poses a significant global health issue, being a major risk factor for cardiovascular diseases, including heart disease and stroke. Despite advancements in therapeutic approaches and public health efforts, the awareness, treatment, and control of hypertension remain suboptimal worldwide. The prevalence of hypertension has been on the rise, especially in low- and middle-income countries, with various lifestyle factors contributing to its increasing prevalence. To address this growing health concern, strategies such as utilizing existing antihypertensive agents more effectively, developing novel therapeutic agents, and exploring nonpharmacological approaches are being pursued to improve blood pressure control and reduce the associated cardiovascular risks.
How does hypertension impact public health?5 answersHypertension significantly impacts public health by being a major cardiovascular disease risk factor with implications on morbidity and mortality. It is associated with a range of adverse outcomes, including cardiovascular diseases like atherosclerosis, stroke, and heart failure, contributing to high mortality rates globally. The prevalence of hypertension poses a substantial burden on healthcare systems, with significant costs attributed to uncontrolled hypertension. Despite efforts to increase awareness, treatment, and control rates, there is still a need for sustainable interventions to combat the rising tide of hypertension prevalence. Public health programs focusing on lifestyle modifications, education, and integrated care models involving various stakeholders are crucial in addressing the challenges posed by hypertension and improving the quality of life and healthy life expectancy.
How does prevalence of hypertension?4 answersThe prevalence of hypertension is increasing worldwide, with disparities between countries. Low- and middle-income countries are experiencing the highest increase in prevalence. In the US, the prevalence of hypertension among adults aged 18 years and older was 39.5%, representing an estimated 92.4 million persons. The prevalence of hypertension is higher in racial/ethnic minority individuals, except for black participants. The prevalence of hypertension also increases with age. Factors such as high salt consumption, low consumption of fruits and vegetables, high alcohol consumption, not maintaining optimal body weight, and low physical activity/sedentary lifestyle contribute to the prevalence of hypertension. Targeted public health efforts are needed to reduce health disparities and decrease the overall population burden of hypertension.
How is hypertension defined?5 answersHypertension is defined as the persistent elevation of blood pressure above normal limits. It can be classified into primary hypertension, which is caused by genetics and environmental factors, and secondary hypertension, which is caused by underlying medical conditions and medications. The concept of hypertension was first described by Richard Bright in the early 1800s, characterized by gradual deterioration, left ventricular hypertrophy, and failure, with albuminuria and a peculiar pulse waveform. Psychological factors such as negative affect, suppressed hostility, and cognitive functioning have also been associated with hypertension. Blood pressure is measured as the pressure exerted by blood against the walls of arteries, and antihypertensive drugs can help in controlling high blood pressure. Hypertension is currently defined as a blood pressure greater than 140/90 mmHg and is the most common risk factor for stroke.
