Therapeutic inertia, where patients with high cardiovascular risk do not receive timely lipid-lowering treatment intensification, leads to an avoidable atherosclerotic burden. Addressing this gap is crucial for preventing cardiovascular events and reducing healthcare costs.
Area of Science:
- Cardiology
- Preventive Medicine
- Health Services Research
Background:
- Therapeutic inertia in lipid-lowering treatment is a paradox in cardiovascular medicine.
- Most high-risk patients do not achieve guideline-recommended LDL-cholesterol targets.
- This gap between evidence and practice leads to avoidable atherosclerotic burden.
Purpose of the Study:
- To examine therapeutic inertia in lipid-lowering treatment for secondary cardiovascular prevention.
- To describe its epidemiology, mechanisms, and clinical consequences.
- To propose clinician phenotypes and the concept of avoidable atherosclerotic burden.
Main Methods:
- Narrative review of contemporary European and international data.
- Analysis of physician-, patient-, and system-level determinants of inertia.
- Characterization of clinician phenotypes and the concept of avoidable atherosclerotic burden.
Main Results:
- Fewer than one-third of secondary prevention patients achieve LDL-C targets.
- Therapeutic inertia contributes to cumulative vascular injury and increased cardiovascular events.
- Clinician phenotypes and system-level factors perpetuate inertia.
Conclusions:
- Overcoming therapeutic inertia is a clinical and ethical imperative.
- Strategies like upfront combination therapy and AI can shift lipid management to proactive care.
- Transforming optimal lipid management into a system-level default is essential.

Moment of Inertia
If a rigid body is rotating about an axis but is not in translational motion, its translational kinetic energy is zero. However, since each particle undergoes rotational motion, it possesses non-zero velocity and kinetic energy. Thus, the kinetic energy of the rigid body, which is the sum of the...
Inertia Tensor
The diagonal components of the inertia tensor matrix represent the moments of inertia concerning the principal axes of the object. These primary axes are defined as the axes where the object experiences the least...
