Infective endocarditis risk factors
Risk factors:
- Prosthetic valves, foregoing bodies, acquired valvular disease, mural thrombus, HCM, conditions predisposed to infection
Most commonly seen in pt with MVP with MR or AS
Symptoms in infective endocarditis
fever, chills fatigue arthalgia, myalgia night sweats paleness weight loss hematuria splenomegaly
New heart murmur: regurgitation Embolic event sepsis microhematirua fever of unknown origin in case of: new AV block, new HF, peripheral abscess, previous IE, intracardiac material
Special signs in endocarditis
Janeway lesion: erythematous, hemorrhagic/pustular lesion on palms/soles
Osler-node: tender, subcut nodules in pulp of digits or thenar (immune complex depositions)
Roth’s spots: conjuctive petechiae. Retinal haemorrhage with white center
Diagnostics of endocarditis
Duke criteria
Positive blood culture
Echo - vegetation, perivalvular abscess, new valvular regurgitation.
minor crit:
- janeway, fever. osler roths spots, glomerulonephritis
Congenital heart disease in adults
- Patent ductus arteriosus
- Aortic coarctation
- Tetralogy of ballot
- Transposition of the great arteries
- Pulmonary stenosis
- Ebsteins anomality of the tricuspid valve
Arterial septal defects
- Ostium secundum arterial septal defect
- patent foramen ovale
- Ostium primum arterial septal defect
- Sinus venosus defect
- Common or single atrium
ventricular septal defects
Most common congenital abnormality.
Ass with downs syndrome
Many close spont
L ->R
Drug treatment of HT
Monotherapy
- CCB (elderly)
- ACEi( young) /ARB
- BB (pregnant)
Combination
- ACEi + CCB + Thiazide diuretics
Diuretics and BB ↓ mortality
Types of anticoagulants
Heparin - bind ATIII, mesure aPTT (n: 30-50s)
LMWH - only fX
Direct thrombin inhibitors (e.g dabigatrin)
Direct oral factor Xa inhibitors
Warfarin (Vit K dep factors: VII, IX, X, thrombin)
Thrombolytic agents
TPA
Streptokinase
Antiplatelet drugs
Aspirin - Block COX Glycoprotein IIB/IIIa - Block platelet cross-linking Clopidogrel - Prevent ADP mediated aggregation Dipyridamole - inhibit PDE; inhibit platelet aggregation, and creates vasodilation - also inhibit uptake of adenosine
