Insights

Dyslipidemic hypertension (DH), affecting 1 in 6 adults, significantly increases cardiovascular disease (CVD) risk compared to simple hypertension. DH patients face nearly half the CVD risk attributed to metabolic syndrome.

Area of Science:

  • Cardiology
  • Metabolic Disorders
  • Epidemiology

Background:

  • Investigated cardiovascular disease (CVD) prevalence, features, and risk in dyslipidemic hypertension (DH).
  • Defined DH using blood pressure, triglycerides, and HDL-cholesterol per National Cholesterol Education Program guidelines.
  • Distinguished DH from simple hypertensives (SH) based on these criteria.

Purpose of the Study:

  • To assess the CVD risk associated with dyslipidemic hypertension (DH).
  • To characterize the features of DH.
  • To compare CVD risk in DH versus simple hypertensives (SH) and metabolic syndrome.

Main Methods:

  • Prospective population-based study of 2225 adults free of CVD at baseline.
  • Follow-up for a mean of 4.1 years, recording fatal and nonfatal CVD events.
  • Defined DH, SH, and normotensive groups; assessed metabolic syndrome prevalence.

Main Results:

  • DH individuals exhibited higher BMI, apolipoprotein B, fasting insulin, glucose, and C-reactive protein than SH.
  • Cox regression revealed a 1.57-fold higher hazard ratio (HR) for CVD in DH versus SH, adjusted for key factors.
  • DH showed a 1.45-fold higher adjusted HR for CVD compared to other subjects with metabolic syndrome.

Conclusions:

  • Dyslipidemic hypertension (DH), prevalent in 16% of adults, presents distinct features and elevated CVD risk.
  • DH confers a higher CVD risk than simple hypertension (SH).
  • DH carries approximately half the attributable cardiovascular risk associated with metabolic syndrome.

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...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Coronary Artery Disease I: Introduction

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...

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...
Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
