高血压的病因及治疗

Abstract

Hypertension is a prevalent chronic disease that has become the leading cause of cardiovascular disease worldwide. Understanding the underlying causes of hypertension and effective treatment methods for this disease is necessary. This paper aims to explore the causes and treatments of hypertension with a comprehensive examination of its pathophysiology, clinical manifestations, and conventional therapies. The conclusion proposed that a comprehensive therapeutic approach, including lifestyle modifications, medication, and regular monitoring of blood pressure, is essential to the effective management of hypertension.

Introduction

Hypertension, also called high blood pressure, is defined as a systolic blood pressure of ≥140mmHg and/or diastolic blood pressure of ≥90mmHg. It is a chronic disease that is highly prevalent worldwide, affecting approximately one billion people. Hypertension is classified as primary or secondary. Primary hypertension accounts for 90% to 95% of hypertensive cases and has no identifiable cause. In contrast, secondary hypertension is due to the underlying medical condition, such as renal, endocrine, or cardiovascular disease. Hypertension is one of the leading causes of cardiovascular, cerebral, and renal diseases, leading to high morbidity and mortality.

Pathophysiology

Hypertension is multifactorial and involves complex interactions between genetic and environmental factors. The exact pathophysiological mechanisms of hypertension remain unclear, but several theories have been proposed, including sympathetic nervous system activation, renin-angiotensin-aldosterone system (RAAS), endothelial dysfunction, and genetic factors.

Clinical Manifestations

Hypertension is asymptomatic, and most people do not experience any symptoms until the disease is in advanced stages. When symptoms occur, it typically includes headaches, dizziness, fatigue, vision problems, chest pain, and shortness of breath. However, hypertension is often referred to as the "silent killer" because it can cause long-term damage to the body without any noticeable signs.

Treatment

The primary goal of hypertension management is to lower blood pressure and prevent complications such as heart attack and stroke. The treatment approach includes lifestyle changes, medications, and regular blood pressure monitoring.

Lifestyle modifications are essential in hypertension management. These changes include losing weight, reducing salt intake, exercising regularly, reducing alcohol consumption, and quitting smoking. An increased intake of fruits, vegetables, and fiber has been found to lower blood pressure.

Pharmacological treatment for hypertension includes diuretics, calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors, and angiotensin receptor blockers (ARBs). The drug and dosage regimen depend on the severity and underlying conditions of hypertension.

Regular monitoring of blood pressure is critical in the management of hypertension. The target blood pressure varies depending on the individual's age, sex, and concomitant illnesses such as diabetes.

Conclusion

Hypertension is a prevalent chronic disease associated with significant morbidity and mortality. The pathophysiological mechanisms of hypertension are complex, but several theories have been proposed, including sympathetic nervous system activation and RAAS. Treatment of hypertension includes lifestyle
