Question | Answer |
---|---|
Composed of the heart, arteries, capillaries, and veins. transports nutrients to tissues and removes wastes from tissues | cardiovascular system |
abnormal heart rhythm or heartbeats occur and vary from the normal orderly sequence. this can reduce the heart's ability to pump blood. | arrythmia |
chest pain is caused by an insufficient amount of oxygenated blood reaching the heart muscle. | angina |
an infection involving the heart | endocarditis |
being obtained from the digitalis plant and exert powerful action on the heart, it also increases the muscle's contraction and improves irregular heartbeats | cardiac glycosides |
uses for cardiac glycosides | treat congestive heart failure and some arrhythmias |
mechanism of action for cardiac glycosides | unknown, but cardiac glycosides increase the contraction of the heart |
side effects of cardiac glycosides | nausea/vomiting, confusion, arrhythmias, yellow/green halos, low therapeutic index |
digoxin | lanoxin, digitex |
uses for antiarrhytmics | help to restore and maintain normal heart rhythms |
mechanism of action for antiarrhythmics | multiple classes have different effects on the heart to affect its rhythm |
side effects of antiarrhythmics | nausea/vomiting, confusion, arrythmias |
lidocaine | xylocaine |
procainamide | procan |
quinidine | quinidex |
amiodarone | cordarone |
flecainide | tambocor |
propafenone | rythmol |
uses for antianginals | treats angina |
mechanism of action for antianginals | decreases the amoun tof blood that returns to the heart, decreasing the heart rate or decreasing the resistance to pump, and decreases the amount of work for the heart |
side effects for antianginals | dizziness, low blood pressure, and headaches because of dilation of blood vessels |
nitroglycerin | nitrostat |
isosorbide dinitrate | osordil |
isosorbide mononitrate | imdur |
why should nitroglycerin not be stored in soft plastic | because nitroglycerin readily undergoes absorption to many soft plastics |
uses for vasodilators | treats peripheral vascular disease caused by arteriosclerosis and advanced diabetes |
mechanism of action for vasodilators | dilate peripheral blood vessels, increase blood flow to extremities by relaxing the smooth muscle of the blood vessels |
side effects of vasodilators | tachycardia (increased heart rate) |
hydralazine | apresoline |
uses for PDE-5 meds | treats erectile dysfunction, treat pulmonary arterial hypertension (PAH) |
mechanism of action for PDE-5 | a PDE-5 inhibitor works to increase blood flow in the penis through vasodilation. PDE-5 is also used to treat pulmonary arterial hypertension |
side effects of PDE-5 | appear to be dose related: headache, dizziness, flushing, dyspepsia, nasal congestion, rhinitis |
contraindications | PDE5 inhibitors are contraindicated in patients taking nitrate medication. They are also contraindicated in men for whom sexual intercourse is inadvisable because of cardiovascular risk factors. |
sildenafil | viagra |
tadalafil | cialis |
vardenafil | levitra |
uses for calcium channel blockers | treat hypertension and angina |
mechanism of action for calcium channel blockers | dialate coronary arteries, reduce oxygen demand on the heart, and decrease heart rate; ccblockers work by blocking voltage-gated calcium channels in cardiac muscle and blood vessels |
side effects of calcium channel blockers | constipation |
nifedipine | procardia |
verapamil | calan, isoptin |
diltiazem | cardizem |
amlodipine | norvasc |
felodipine | plendil |
uses for angiotensin-converting enzyme (ACE) inhibitors | treat hypertension and congestive heart failure |
mechanism of action for angiotensin-converting enzyme (ACE) inhibitors | prevents the conversion of angiotensin 1 and angiotensin 2 |
side effects of ACE inhibitors | cough [if the cough persists then try a different one]; rash/swelling |
captopril | capoten |
enalapril | vasotec |
lisinopril | zestril, prinivil |
benazepril | lotensin |
fosinopril | monopril |
quinapril | accupril |
ramipril | altace |
moexipril | univasc |
trandolapril | mavik |
angiotensin 2 inhibitors uses | treats hypertension and congestive heart failure |
mechanism of action for angiotensin 2 inhibitors | inhibits angiotensin 2 and reduces vasoconstriction and blood pressure |
losartan | cozaar |
valsartan | diovan |
irbesartan | avapro |
uses for beta-adrenergic blockers | treats hypertension and angina |
mechanism of action for beta-adrenergic blockers | inhibits the action at the beta receptors on the heart; some are selective for the beta cells only on the herat, while others are non-selective and can act in other places within the body, e.g. lungs |
side effects of beta-adrenergic blockers | hypotension, bronchocontriction [not used with asthma patients-if used, must be with caution], dizziness |
atenolol | tenormin |
metoprolol | lopressor |
propranolol | inderal |
nadol | corgard |
sotalol | betapace |
acebutolol | sectral |
labetolol | trandate |
bisoprolol | zabeta |
alpha-adrenergic blockers uses | treat hypertension, severe congestive heart failure, and benign prostatic hyperplasia (BPH) |
mechanism of action for alpha-adrenergic blockers | inhibits the action at the alpha receptors in the blood vessels |
side effects of alpha-adrenergic blockers | orthostatic hypotension and dizziness |
prazosin | minipress |
terazosin | hytrin |
doxazosin | cardura |
tamsulosin | flomax |
uses for antilipidemic agents | treat heart disease and high cholesterol |
mechanism of action for antilipidemic agents | reduces serum lipids and minimizes the rate of new fat deposition; decreases LDL, decreases triglycerides |
side effects of antilipidemic agents | diarrhea, constipation, flushing |
lovastatin | mevacor |
gemfibrozil | lopid |
cholestyramine | questran |
pravastatin | pravachol |
simvastatin | zocor |
atorvastatin | lipitor |
fluvastatin | lescol |
fenofibrate | tricor |
