Silent Heart Threat: 8 Million Canadians at Risk
26 Apr
Summary
- One in five Canadians, about eight million people, have high Lp(a).
- Elevated Lp(a) significantly increases heart attack and stroke risk.
- Experts urge routine screening for this genetically linked particle.
New guidance from Canadian experts aims to raise awareness of Lipoprotein(a) (Lp(a)), a common but often unknown risk factor for heart attack and stroke. Research indicates that about one in five Canadians, totaling roughly eight million individuals, possess high levels of this particle, which is primarily genetically determined. Elevated Lp(a) poses a significant danger as its sticky nature promotes plaque buildup in blood vessels, potentially leading to heart attacks or strokes.
Experts emphasize the need for a one-time screening for all Canadian adults, a recommendation echoed by recent guidance from the American College of Cardiology. While lifestyle changes do not lower Lp(a) levels, understanding one's risk is crucial. For those with elevated levels, statin medications are typically prescribed to manage other cholesterol types, thereby compensating for the Lp(a) risk. Ongoing research is exploring specific medications to directly target Lp(a).
Individuals with a family history of high Lp(a), or those with certain health conditions like known heart disease, stroke, or kidney problems, are particularly encouraged to get tested. Furthermore, people of African, Caribbean, or South Asian descent are noted to have a higher likelihood of elevated Lp(a) levels. A simple blood test, covered by all Canadian provinces, can identify these elevated levels, empowering individuals and their healthcare providers to better manage cardiovascular health.
