Low-dose aspirin.
From various studies have shown that
aspirin is still the main drug for the prevention of thrombosis. Meta-analysis
showed that a dose of 75-150 mg have similar effectiveness when compared with
larger doses. Recommended for all patients were given aspirin except when
contraindicated found. In addition aspirin is also recommended given the long
term, but keep in mind the side effects of gastrointestinal irritation,
bleeding and allergies. Cardioaspirin provide a more minimal side effects
compared with other aspirin.
Clopidogrel
dan Ticlopidine Thienopyridine
an ADP antagonist and inhibits
platelet aggregation. Clopidogrel is more indicated in patients with aspirin
resistance or intelorensi against. AHA / ACC guidelines include a combination
of aspirin and clopidogrel should be given to patients with stent implantation,
more than 1 month for bare metal stent, 3 months for sirolimus eluting stents,
and over 6 months for paclitaxel-eluting stents.
Cholesterol-lowering drugs
Treatment with statins are used to
reduce the risks to both primary prevention and secondary prevention. Various
studies have shown that statins can reduce complications by 39% (Heart
Protection Study), Ascott-LLA atorvastatin for primary prevention of coronary
heart disease in post-hypertension. Than as a cholesterol-lowering statins also
have other mechanisms (pleiotropic effect) that can act as an
anti-inflammatory, anti-thrombotic and others. Giving atorvastasin 40 mg for
one week can reduce the myocardial damage caused by the action. The target
reduction in LDL cholesterol is <100 mg / dl and in patients at high risk.
Patients with coronary heart disease is recommended lowering LDL cholesterol
<70 mg / dl.
ACE-Inhibitor/ARB
The role of ACE-I as a cardio
protection for secondary prevention in patients with coronary heart disease has
been demonstrated from various studies ai, HOPE study, EUROPE study and others.
If intolerance to ACE-I can be replaced with ARB.
Nitrate
Nitrate is generally recommended,
because nitrate has venodilator effect, so that myocardial preload and left
ventricular end volume decreases and thus the amount of myocardial oxygen
consumption also decreases. Nitrates also dilate blood vessels to be normal and
atherosclerotic experience. Raising the collateral blood flow and inhibits
platelet aggregation. When an attack of angina does not respond to short-term
nitrate, then be aware of the existence of myocardial infarction. Side effects
of this drug are headache and flushing.
