Question | Answer |
Historically the clinical diagnosis of an acute MI requires two of what three findings | Chest pain, Characteristic EKG changes, and increased serum enzymes |
Diseases affecting cardiac muscle cause an increase in what CK enzymes | CK MM and MB (MI, Trauma to the heart) |
Disorders affecting the skeletal muscle cause an increase in what CK enzymes | CK MM (Dystrophies, trauma, Hypothyroid, stroke, psychoisis) |
Diseases affecting smooth muscle cause and increase in what CK enzymes | Increased CKBB (labor and delivery, Intestinal infarct, shock) |
How long after the onset of symptoms (of MI) do CK and CKMB become abnormal | 8 hours (peak within 36 hours) |
when do CK enzymes return to normal after a MI | within 2-3 days |
what is the most sensitive and specific marker for a MI | Cardiac troponin I and T |
When do cardiac troponins increase after symptoms of an MI | about 8 hours after symptoms |
how long do troponins remain increased after a MI | 7-10 days (continued release not delayed clearance) |
When do CK markers prove more useful than troponins | when you need to detect re-infarct in the acute >3 <10 day period following a MI |
How specific are troponins for coronary artery etiologies of myocardial infarction | they are not specific for coronary artery etiologies of myocardial disease they are increased in cardiac conditions that are associated with myocardial injury such as heart failure and cardiomyopathies |
when are natriuretic peptides A and B increased | in serum in chronic heart failure secondary to enhanced atrial and ventricular synthesis |
where are B-type natriuretic peptides found | in the brain and ventricles of the heart (released in response to ventricular overload) |
where are c-type natriuretic peptides found | in the brain and CNS released in response to endothelial stress |
When is BNP used | in diagnosis of heart failure in ED patients, Monitoring therapy of heart failure, prognosis in acute coronary syndromes |
Where is CRP produced | in the liver |
when is CRP increased | with inflammation (used as a nonspecific test for infection) |
How can CRP be used to assess risk of MI | atherosclerosis increases CRP |
