Diagnosis of MI

Cardiac troponin I is used within the 1st -?-4 hours up to 7-10 days; more specific than other -?-protein markers.

-?-CK-MB is test of choice in the first 24 hours post-MI

-?-dilated etiologies include chronic alcohol abuse, beriberi, postviral myocarditis by coxsackievirus B, chronic cocaine use, Chagas' disease, doxorubicin toxicity, peripartum cardiomyopathy
-?-hypertrophic cardiomyopathy diastolic dysfunction ensues
-?-dilated systolic dysfunction ensues
-?-dilated heart dilates and looks like a balloon on chest X-ray
dilated hypertrophic cardiomyopathy restrictive/obliterative cardiomyopathy

Matching: Heart murmurs

-?-aortic stenosis Crescendo-decrescendo systolic ejection murmur following ejection click
-?-mitral stenosis Continuous machine-like murmur; loudest at time of S2
-?-aortic regurgitation Immediate high-pitched "blowing" diastolic murmur; wide pulse pressure
-?-mitral regurgitation Holosystolic high-pitched "blowing" murmur
-?-PDA Follows opening snap; delayed rumbling late diastolic murmur
-?-VSD Holosystolic murmur
-?-mitral prolapse Late systolic murmur with midsystolic click; most frequent valvular lesion
mitral regurgitation aortic stenosis VSD mitral prolapse aortic regurgitation mitral stenosis PDA

Cardiac tumors

-?-myxomas are the most common 1° cardiac tumor in adults; -?-90% occur in the atria; usually are described as a " -?-ball valve" obstruction in the LA.

-?-rhabdomyomas are the most frequent 1° cardiac tumor in children.

-?-metastases are the most common heart tumor.

CHF/ abnormality → cause

Abnormality Cause
Ankle, sacral, eduma -?-RV failure → ↑ venous pressure → fluid transudation
Hepatomegaly (nutmeg liver) -?-↑ central venous pressure → ↑ resistance to portal flow; rarely, leads to cardiac cirrhosis
Pulmonary congestion -?-LV failure → ↑ pulmonary venous pressure → pulmonary venous distention & transudation of fluid; presence of hemosiderin-laden macrophages (heart failure cells)
Dyspnea on exertion -?-Failure of LV output to ↑ during exercise
Paroxysmal nocturnal dyspnea, pulmonary edema -?-Failure of left heart output to keep up with right heart output → acute rise in pulmonary venous & capillary pressure → transudation of fluid
Orthopnea (shortness of breath when supine) -?-Pooling of blood in lungs in supine position adds volume to congested pulmonary vascular system; ↑ venous return not put out by LV
Cardiac dilation -?-Greater ventricular end-diastolic volume

Embolus types:

"An embolus moves like a FAT BAT." What does this mnemonic stand for? -?-Fat, Air, Thrombus, Bacteria, Amniotic fluid, Tumor

Fat emboli are associated with long bone fractures and -?-liposuction.

Amniotic fluid can lead to DIC, especially -?-postpartum

Pulmonary embolus are associated with chest pain, tachypnea, and -?-dyspnea

Approximately -?-95% of pulmonary emboli arise from deep leg veins.

Deep venous thrombosis: predisposed by Virchow's triad

s -?-statis
h -?-hypercoagulability
e -?-endothelial damage

Bacterial endocarditis:

-?-mitral valve is most frequently involved

Late sequelae include rheumatic heart disease,which affect heart valves - mitral > aortic >> -?-tricuspid

Associated with -?-Aschoff bodies, migratory polyarthritis, erythema marginatum, elevated -?-ASO titers
