Cardiac Flashcards
BP formula
BP= HR x SV x PR (peripheral resistance)
* Increase in any part of the formula, BP rises. Decrease in any part of the formula BP falls
Cardiac output
Amount of blood the heart pumps through the circulatory system in 1 minute.
BP goal for pts >60
BP goal for pts
HTN treatment for pts for non-black pts
Thiazide-type diuretic or ACEI or ARB or CCB, alone or in combination
HTN treatment for black pts
Thiazide-type diuretics, or CCB, alone or in combination.
HTN treatment for CKD pts with or without DM
ACEI or ARB, alone or in combination
Thiazides
HCTZ, chlorthalidone
*monitor Na+, K+, Mg+ depletion.
Less effective with advanced renal impairment.
Contraindicated with GOUT due to increases in Uric acid
ACEI
“Prils” Lisinopril, enalapril
*pregnancy category D
Modest hyperkalemia risk , ACEI related cough
ARBS
“Sartans” losartan, telmisartan
Pregnancy category D
CCB
Dihydropyridine (DPH) “Ipines”amlodipine
Non DPH- Ditalazem, verapamil
*caution with non DPH use due to CYP450 3A4 inhibition (especially with the use of select statins
Avoid use in presence of heart failure, renal or hepatic impairment
Malignant HTN
Rapidly progressive HTN
Diastolic usually >140
Can lead to encephalopathy
Dyslipidemia
A disorder of lipoprotein metabolism.
Increased total cholesterol, LDL, decreased HDL.
Excess circulating cholesterol can lead to plaque formation.
Meds that can cause secondary dyslipidemia
Beta-blockers
Thiazide diuretics
Antiretroviral drugs
Hormonal agents
Recommend 4 groups for statin therapy
Adults with clinical ASCVD
Adults with LDL-C >190mg/dl
Adults 40-75 years with DM
Adults with >7.5% estimated 10 year risk of ASCVD
LDL classifications
190 Very high
HDL classifications
60 High
Medications for dyslipidemia
- HMG-CoA reductase inhibitor (Statin)
- Bile acid resins (sequestrants)
- Niacin
Classification of triglycerides
500 Very high (diet & intensive meds)
Causes of elevated triglycerides
Overweight & obesity Physical inactivity Cigarette smoking Excess ETOH High carb diets T2DM, CKD, nephrotic syndrome Steroids, estrogens, retinols, beta blockers
Drug of choice for high triglycerides
Fibrin acid derivatives (fibrates)
Ex- Gemfibrozil (Lopid), fenofibrate (Tricor)
Other meds for high triglycerides
Niacin (ex-niacin, niaspan) decreases 20-50%
Fish oil (omega-3 fatty acid) decreases 20-30%
Mgmt For very high triglycerides
Goal is to prevent acute pancreatitis.
Treat triglycerides before LDL
