11 chronic ischemic heart disease Flashcards
what are the chronic ischemic heart disease ?
stable angina pectoris
silent myocardial ischemia
causes atleast 7 percent of lumen obstruction
has not ruptured artheroscleroti plaque
only as world increases the blood flow becomes not sufficient anymore leading to angina
patent take rest or nitroglycerin the workload f the heart decreases
what is the clinical presentation of chronic ischemic heart disease ?
duration 5-15 mins- same every time , same intensity , radiates to same location
what can be diagnosis of chronic ischemic heart disease ?
ST segment depression
at j point beginning of affected area
T wave negative symmetrically ascending and descending limbs
egg after attack normal - because only causes reversible damage
echcardiogram ultrasound - during attach
segemntal kinetic diturbances
impaired left ventricular relaxation
outside attack normal
an attack of stable angina is provoked - treadmill stress with simultaneous egg recordings
perfusion myocardial scintography
invasive testing - selective coronary artery angiography
inserted into femoral artery the catheter
introduce contrast die to coronary artery - x ray
what is the treatment of patient with stable angina attacks ?
anti platelet drugs
aspirin - gi ulcerations and bleeding
contraindicated - peptic ulcers,
Reye’s syndrome, a rare but severe illness characterized by acute encephalopathy and fatty liver
clopidrogel if aspirin allergy
thrombotic thrmobocytopnic purpura
lipid lowering
statin
permanent duration again - because of rebound phenomena esp in statins
fluvastatin
rabhdomyolysis , myaligia
no interaction with CYP3A4 - but simvastatin does
fibrates (fenofibrate) with nicotonic acid
fenofibrate - nephro and hepatotoxicity
ACE-I
—————–
betablockers
symptom reducing
symtoms are relieved by reduced oxygen demand
preload reduction
after load rduction
heart rate and contractility reduction
preload reduction
short acting nsublingual nitrates
long acting - mononitrate , denigrates
causes headaches - due to increased intrcranila pressure
contraindicated when increased intraocular pressure
after load reduction -
ACE-I
calcium channel blockers
heart rate reduction
B 1 selective blockers
STENT - only done when persisting symptoms
mediteranian diet
