Nursing Pharmacology Chapter 9: Antianginal Drugs
Angina: Treatment Objectives and Approaches: Treatment objectives include both acute management and prevention of anginal episodes:
These agents cause systemic venodilation and therefore reduce myocardial wall tension and oxygen requirements
Nitrates dilate epicardial coronary capacitance vessels thereby increasing blood flow in collateral vessels.
Although other nitrates may be used in management of angina, other preparations are less effective in acute management.
Medical management is individualized for each patient, including patient education and counseling to assist in reduction of risks of coronary heart disease.
Risk management includes:
Optimal treatment or elimination of co-existing illness such as diabetes mellitus and hypertension.
Dietary and drug therapy of dyslipidemias
Adapation of activities, such as increasing the amount of time needed to accomplish a task which if performed more rapidly could induce angina.
