Cardiology Flashcards
Bivalirudin- what is it and when is it used
IV direct thrombin inhibitor,
Used as anticoagulation for patients undergoing PCI
Strep Bovis- strep gallolyticus- what is its relation to endocarditis
most common cause of colorectal Ca related Infective endocarditis
Infective Endocarditis- first line treatment
NSAIDS+Colchicine
most sensitive sign for IE on ECG
PR depression
acute vasodilator testing- what is it used for
- for splitting patients management into 2 groups in Pulmonary hypertension
+ve vasodilator therapy- calcium channel blockers - ve vasodilator therapy-Prostacyclin analogues-treprostinil, iloprost, Endothelin receptor antagonists-bosentan, ambrisentan
Phosphodiesterase inhibitors- sildenafil
absent limp pulse(varying blood pressure in both limbs) + chest pain on exertion
Takayasu’s arteritis
narrow pulse pressure, slow rising pulse, S4 heart sound- which pathology
Aortic Stenosis
wide pulse pressure, S3 heart sound
Aortic regurgitation
harsh mid ejection systolic murmur louder on inspiration and associated with carcinoid heart disease(Hedinger Syndrome)
Pulmonary stenosis
what develops if an left to right shunt(VSD,AVSD, PDA) is left unrepaired
leads to eisenmengers syndrome(shunt reversal) which needs heart-lung transplant
example of a phosphodiesterase inhibitor used in TIAs
Dipyridamole
management of Prinzmetal angina
dihydropyridine calcium channel blocker-felodipine
Indications for a temporary pacemaker
symptomatic/haemodynamically unstable bradycardia, not responding to atropine
post-ANTERIOR MI: type 2 or complete heart block*
trifascicular block prior to surgery
why dont you pace someone who has complete heart block following Inferior MI which was PCId
PCI can revascularise the right coronary artery and thereby revascularise the AV node
what is the sign that differentiates MR from TR
carvallo sign(inspiration makes tricuspid regurgitation louder)
