Insights

Hypertension-related cardiovascular disease mortality varies significantly among Asian American subgroups, with all groups showing higher proportional mortality than non-Hispanic White individuals. This highlights disparities in cardiovascular health outcomes within the Asian American population.

Area of Science:

  • Public Health
  • Cardiovascular Epidemiology
  • Health Disparities

Background:

  • Cardiovascular disease (CVD) mortality shows heterogeneity across Asian American subgroups.
  • Differences in hypertension-related CVD mortality among these subgroups remain largely unknown.

Purpose of the Study:

  • To investigate and compare hypertension-related CVD mortality rates and proportional mortality across diverse Asian American subgroups in the United States.
  • To identify variations in mortality risks associated with hypertension within the Asian American population.

Main Methods:

  • Utilized US mortality data from 2018-2021, focusing on deaths with CVD as the underlying cause and hypertension as a contributing factor.
  • Compared sex-specific, age-standardized mortality rates, proportional mortality, and proportional mortality ratios for non-Hispanic Asian subgroups, Hispanic, and non-Hispanic Black individuals against non-Hispanic White individuals.

Main Results:

  • Significant variation in hypertension-related CVD mortality was observed among Asian American subgroups, with up to a two-fold difference.
  • All Asian American subgroups exhibited higher proportional mortality for hypertension-related CVD compared to non-Hispanic White individuals.
  • Specific subgroup data revealed varying mortality rates, e.g., Filipina females (52.6/100,000) and Filipino males (81.0/100,000) showed higher rates.

Conclusions:

  • Hypertension-related CVD mortality is not uniform across Asian American subgroups, indicating significant internal disparities.
  • All examined Asian American subgroups face a disproportionately higher burden of mortality from hypertension-related CVD compared to the non-Hispanic White population.

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
