Insights

Low-density lipoprotein cholesterol (LDL-C) goal attainment is poor in Taiwanese patients with atherosclerotic cardiovascular disease (ASCVD). Intensified lipid management and adherence to therapy are crucial for secondary prevention of cardiovascular events.

Area of Science:

  • Cardiology
  • Public Health
  • Pharmacology

Background:

  • Effective lipid control is vital for secondary prevention of cardiovascular disease (CVD).
  • Low-density lipoprotein cholesterol (LDL-C) goal attainment rates in high-risk Taiwanese patients are not well-established.

Purpose of the Study:

  • To evaluate LDL-C goal attainment and adherence to lipid-lowering therapy (LLT) in Taiwanese patients with atherosclerotic cardiovascular disease (ASCVD).

Main Methods:

  • Retrospective observational study of 116,228 ASCVD patients (2017-2021).
  • Analysis of LDL-C levels, LLT intensity, and goal attainment (< 70 mg/dL).
  • Multivariate logistic regression to identify factors associated with LDL-C goal attainment.

Main Results:

  • Only 12.2% achieved LDL-C < 70 mg/dL at baseline, improving to 25.1% at 12 months.
  • High-intensity LLT significantly increased the likelihood of goal attainment (RR 1.54, p < 0.001).
  • Male sex, diabetes, and prior PCI were positively correlated with goal attainment, but control remained suboptimal in cerebrovascular and peripheral artery disease subgroups.

Conclusions:

  • Real-world LDL-C goal attainment in Taiwanese ASCVD patients is low.
  • There is a need for intensified lipid management and improved adherence to guideline-based therapy.
  • Tailored interventions are necessary for non-CAD ASCVD patients to reduce cardiovascular risk.

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
Actuarial Approach01:20

Actuarial Approach

The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

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...
