After a referral from the emergency department to the cardiology department, a Permanente Group cardiologist performed a left heart catheterization that ruled out coronary artery disease but failed to perform the right heart catheterization which would have shown a potentially fatal pulmonary embolism. (walkuplawoffice.com)
The most common form of heart disease is coronary artery disease in which plaque (a fat-like substance) deposits on artery walls. (womensheart.org)
When a plaque ruptures, it causes a blood clot to form and suddenly block an artery. (womensheart.org)
If this happens in a heart artery, it results in a heart attack. (womensheart.org)
