Insights

Anti-hypertensive and hypolipidaemic drugs prevent coronary heart disease (CHD). New guidelines target high-risk patients, incorporating novel factors like C-reactive protein for improved risk prediction and intervention.

Area of Science:

  • Cardiology
  • Preventive Medicine
  • Clinical Risk Assessment

Background:

  • Evidence supports anti-hypertensive and hypolipidaemic drugs for coronary heart disease (CHD) prevention.
  • International guidelines recommend specific blood pressure (<140/90 mm Hg) and LDL-cholesterol (<2.6 mmol/l) targets for manifest CHD.
  • Secondary prevention strategies now focus on pre-symptomatic, high-risk individuals.

Purpose of the Study:

  • To outline current guidelines for CHD prevention, including tertiary and secondary prevention.
  • To detail the conventional risk factors used in CHD risk assessment.
  • To explore the role of novel risk factors, such as C-reactive protein, in refining risk prediction.

Main Methods:

  • Review of controlled interventional trials and international guidelines for CHD prevention.
  • Description of conventional cardiovascular risk factors (sex, age, smoking, diabetes, lipids, blood pressure).
  • Discussion of risk scores and algorithms for calculating absolute myocardial infarction risk.
  • Evaluation of C-reactive protein as a novel risk factor for improving prognostic value.

Main Results:

  • Established guidelines recommend strict blood pressure and LDL-cholesterol control in patients with CHD.
  • Risk stratification for secondary prevention involves assessing morbidity risk (>20%) and mortality risk (>5%) over 10 years.
  • Conventional risk factors are used to compute absolute myocardial infarction risk.
  • High C-reactive protein levels enhance the prognostic value of global risk estimates, particularly for intermediate-risk patients.

Conclusions:

  • Current guidelines effectively manage manifest CHD and identify high-risk pre-symptomatic individuals.
  • Novel risk factors, like C-reactive protein, offer potential to improve cardiovascular risk prediction and guide treatment decisions.
  • Accurate risk assessment is crucial for tailoring preventive strategies in coronary heart disease.

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 II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
