First Aid Flashcards
Disease that affects small/medium vessels and causes fibrinod necrosis.
PAN
Eosinophillic inflitrate with necrotizing vasculitis of smaller vessels. Associated with? (2)
Churg-Strauss. Asthma and Hep B
Patient over 50 with grnulomatous inflammation of vessels, fever and headache?
Giant cell arteritis
Wegner’s - type of giant cells associated with it?
Langerhan’s
Most likely cause of poor feeding, agitation and cyanosis within first few weeks of life? Other congential heart defects that cause cyanosis early in life?
Tetralogy of fallot. (Transposition of great vessels)
Congenital heart defects that present in adulthood?
ASD, PDA
Most common cardiac defect?
VSD
Infant presents with tachypnea, dyspnea and feeding difficulties. Intercostal retractions and hyperdynamic percordium?
ASD
BP drug that is contraindicated if BP is too high?
nifedipine
Lab finding in Takayasu’s
increased ESR
Class III antiarrythmic that does not cause tosades de pointes?
Bretylium
DCM post infection with S3 - Mechanism of heart failure?
Viral Myocarditis. Direct cytotoxicity via receptor-mediated entry of virus into cardiac myocytes.
Causes of DCM
BCCCDEF wet BeriBeri Coxsackie B Cocaine Chagas Doxorubicin Fe
MoA of familial DCM?
Anitbodies to cardiac proteins. Autosomal Dominant
Ganulomatous DCM?
Sarcoidosis
Cocaine cases DCM how?
Hyperadrenergic state
Pt with claudication with smoking hx. What vessel affected?
Arteriosclerosis. Arteries (high turbulence)
JVD that fails to subside with inspiration but no pulsus paradoxis, reduced end-diastolic volumes, and elevated diastolic pressures?
Constrictive pericarditis
Cysic media necrosis
Degeneration of the tunica media of the aorta, a preexisting histo lesion in aortic dissection
MoA of DOC for supraventricular tachycardia?
Adenosine. Very short actiing - increases K efflux - hyperpolarizing cell.
NE - effect on HR?
intropic agent, but vasoconstriction will lead to reflex bradycardia
Vasculature that does not vasoconstrict with NE?
Coronary Arteries
Pt with poorly controlled diabetes and renal failure develops pericarditis. TX?
Dialysis. Pericarditis secondary to uremia.
subacture endocarditis - microbes?
Enterococcus and Viridans
Derivatives of Aortic Arches?
1) Maxillary Artery
2) Stapedial and hyoid
3) Carotid
4) Aorta and Right subclavian
6) Aorta and PDA on left
Sharp high pitched sound in early ventricular diastole, followed by a decrescendo, crescendo murmur.
Mitral Stenosis. Sharp high pitched sound in early ventricular diastole, followed by a decrescendo (slow filling), crescendo (fast filling with atrial kick) murmur.
Decrescendo murmur in early ventricular diastole?
Aortic/Pul regurg
Sharp, high pitched sound in early ventricular systole, followed by a crescendo, decrescendo murmur
Aortic stenosis
Sharp, high-pitched sound in mid ventricular systole, followed by a uniform murmur
Mitral value prolapse and regurg
