Cardio Flashcards
(46 cards)
ACEs (-prils) Uses & MOA
Uses: HTN, angina, prevent/tx HF, prevent MI
MOA: block conversion of angiotensin 1 to 2; breaks down bradykinins
ACE (-prils) Side/Adverse effects
ANGIOEDEMA
orthostatic hypotension
dry, hacking cough (SWITCH TO ARB)
ACE (-prils) Contraindications/Precautions
bilateral renal artery stenosis
angioedema
pregnancy
hyperkalemia
impaired renal function
hypovolemia/hyponatremia
hepatic impairment
ACE (-prils) Interactions
CYP450 inhibitors
additive hypotensive effects (diuretics, BP agents, phenothiazines, alcohol)
K+ supplements = hyperkalemia
K+ sparing diuretics = hyperkalemia
NSAIDs/ASA = DEC effect
ACE (-prils) Monitoring/Patient education
monitor: obtain baseline, dosage changes, periodically; BP, weight, pulse; renal function DEC dose if serum >2.5; potassium
education: take med same time each day, do NOT double dose, CONTACT PCP BEFORE USING OTC MEDS; avoid salt substitutes
ARBs USES & MOA
Uses: HTN, prevent diabetic nephropathy, angina, post MI, HF
MOA: blocks angiotensin 2 at receptor
ARB side/adverse effects
orthostatic hypotension (fall risk)
ARB contraindications/precautions
bilateral renal artery stenosis
angioedema
pregnancy
hyperkalemia
impaired renal function
hypovolemia/hyponatremia
hepatic impairment
ARB interactions
CYP450 inhibitors
additive hypotensive effects (diuretics, BP agents, phenothiazines, alcohol)
K+ supplements = hyperkalemia
K+ sparing diuretics = hyperkalemia
NSAIDs/ASA = DEC effect
ARB Monitoring/patient education
Monitoring: obtain baseline, dosage changes, periodically; BP, pulse, weight; renal function DEC dose if serum >2.5; potassium; CHECK LFTs
education: no reflex tachycardia, no effect on bradykinin pathway, take same time each day, do NOT double doses, CONTACT PCP BEFORE TAKING OTC MED; avoid salt substitutes
DRIs USES/MOA
Uses: HTN, angina, post MI, HF
MOA: block renin
DRI side/adverse effects
ANGIOEDEMA
orthostatic hypotension
DRI contraindications/precautions
NO renal function <60 mL/min
bilateral renal artery stenosis
angioedema
pregnancy
hyperkalemia
impaired renal function
hypovolemia/hyponatremia
hepatic impairment
DRI interactions
CYP450 inhibitors
additive hypotensive agents: diuretics, BP agents, phenothiazines, alcohol
K+ supplements = hyperkalemia
K+ sparing diuretics = hyperkalemia
NSAIDs/ASA = DEC effects
DRI monitoring/patient education
monitoring: obtain baseline, dosage changes, periodically; BP, pulse, weight; renal function DEC dose if serum Cr >2.5; potassium
education: take same time each day, do NOT double doses, CONTACT PCP BEFORE USING OTC MEDS, avoid salt substitutes
CCBs Uses/MOA
Medications: Type 1 (verapamil, diltiazem), Type 2 (dihydropyridines - nifedipine)
Receptors: Type 1 (heart, heart contractility/HR control), Type 2 (peripheral/vascular smooth muscle, BP control)
Uses: HTN, SVT/Afib, unstable angina (only if vasospasm present, verapamil used)
MOA: bind to L-type channels in depolarized membranes to DEC channel opening
DEC calcium = INC muscle relaxation
CCB side/adverse effects
orthostatic sx
N/V, reflux
peripheral edema
reflex tachycardia
LESS COMMON W/ SR FORM
CCB Contraindications/precautions
STRONG INOTROPIC EFFECT & BRADYCARDIA (DEC PRELOAD, AFTERLOAD, HR)
AVOID IN HF
immediate post MI
ventricular arrhythmias
DIHYDROPYRIDINES - AVOID w/ peripheral edema and unstable angina
hepatic impairment
pregnancy
CCB interactions
additive HTN effects
DEC BP w/ NSAIDs
additive bradycardia w/ BBs and digoxin
verapamil alter Li levels
grapefruit juice
VERAPAMIL AND DILTIAZEM INC RISK MYALGIA W/ STATINS
CCB monitoring/patient education
monitoring: verapamil monitor Li levels, LIVER FUNCTION AT BASELINE & PERIODICALLY, monitor for HF
education: take same time each day (best in AM), gradual withdrawal to prevent MI, careful if pharmacy switches brands or old vs new med, HF sx, constipation relief
Cardiac Glycosides (CGs) (Digoxin) Uses/MOA
Uses: Afib, PVST (DEC HR = help convert rhythm); HF (add after ACE/ARB + diuretic in place)
MOA: inhibits Na-K-ATPase pump = keep Na in/push K out = strong ventricular contraction + INC cardiac output
CGs (Digoxin) side/adverse effects
GI- from CNS reactions and stimulus of CTZ
fatigue, disorientation, hallucinations
yellow vision or green halos
gynecomastia = rare
CG (Digoxin) contraindications/precautions
AV block
uncontrolled ventricular arrhythmias
IHSS
Cor pulmonale
severe renal impairment
ELECTROLYTE ABNORMALITIES
DEC albumin states
pregnancy
babies sensitive to dig
CG (Digoxin) Interactions
NARROW THERAPEUTIC INDEX
drugs that cause: hypokalemia, hypercalcemia, hypomagnesemia
K+ and CGs antagonize each other
hypercalcemia = INC risk arrhythmia, as does hypomagnesemia
