Q

What do you use in Atrial fibrillation treatment?

A

Unstable: IV BB (metoprolol-preferred if MI) or IV CCV (diltizem). may need cardioversion (flecanide, dofetalide, propafenone, and ibutilide) if shock, hypotension, pulmonary edema, MI

decrease heart rate and promote conversion to sinus rhymed

Stable: BB (metoprolol) or CCB (diltizem) slow down nodal contraction

Maintenance: BB, CCB, or digoxin (not for pre-excitation AF) combination only in younger patients.

Use BB for hypertensive, CAD, heart failure, and COPD or asthma.

not CCB for CAD, CHF.

critically ill w/out preexcitation can also use amiodarone

Apixaban best choice anticoagulant

Q

What medications would you use in renal disease? what are some indications that that particular drug may not be useful?

A

—Chlorthalidone, HCTZ: ◦Okay to use until CrCl(until the creatinine clearance or glomerular filtration rate)

any of the lipid drugs but fenofibrate and ezemetmibe

19
Q

when are calcium channel blockers useful?

A

afib, angina, COPD

20
Q

when are beta blockers useful?

A

atrial fibrillation, stable heart failure, asymptomatic LV dysfunction

21
Q

what is HFpEF or HFrEF?

A

preserved ejection fraction in diastolic failure reduced ejection fraction in systolic failure

22
Q

what are the L type calcium channels

A

long acting let calcium into the cell triggering additional release from sarcoplasmic reticulum as well as binding allowing it to successfully contract

23
Q

how do you treat acute decompensated heart failure? chronic, compensated heart failure?

A

agressive administrions of congestive features such as pulmonary edema w/ diuresis loss of cardiac output w/ short-term inotropic agents for contractility chronic,compensated- fluid and sodium restrictions, treat comorbidities, and diuresis to avoid triggers

24
Q

what medications slow the SA and AV node?

A

beta-blockers AV node slowing- digoxin

25
Q

what do you use in angina?

A

beta-blockers

26
Q

what do you used in MI?

A

Beta blocker prevent remodeling

27
Q

what are drugs involved in the P450 system?

A

carvedlil P-glycoprotein substrate beta blockers

Class IB- impacted by CYP 450 and P glycoprotein

Class IC- CYP issues for both. propanefone inhibit P-glycoprotein

Class III- amiodarone inhibitor to CYPs and P-glycoprotein impact

Class IV- inhibit CYP and P-glycoprotein

NOACs

28
Q

how does inotropic drugs work?

A
29
Q

describe the stepwise progression of CHF?

A
30
Q

What are the stages and class in combination of heart disease?

A

HFrEF-any cause ACE or ARB avoid CCB and BB

stage B:

  • acute MI- reduced ejection fraction beta blockers.
  • MI- statins
  • HFpEF- bp controlled, diuretics-used for relief of symptoms due to volume, coronary revascularization (angioplasty or bypass) for patients w/ CAD in whom angina or myocardial ischemia is present.
  • ACE or ARBS (decrease hospitilization), beta blocking for hypertension.

stage C

  • present w/ SOB and edema symptoms to get echo.
  • ACE or ARB plus BB
  • Loop diurhetics if volume overload of fluid retention
  • for persistent symptomatic black patients: hydralazine and isosorbide dinitrate
  • if normal renal function can add aldosterone agonist
  • digoxin benficial in patients w/ HFrEF
31
Q

what do the nys guidelines fr hf state?

A

remaining options:

procedures to drain excess fluid-dialysis, pericentesis; continuous inotrop infusion, cardiac transplant, experimental therapies

32
Q

what is the strategy for patients w/ angina?

A

sublingual nitroglycerin> B-blocker (propanolol w/out bronchospastic) >CCB (dihydropyridine: amlodipine-short term; nifedipine- coronary spasm/diltiazem) or isosorbide dinitrate> ranolazine

use long-acting nitrate for every possible disease not CCb for recent MI, not BB for patients feeling hypoglycemic or asthma COPD

33
Q

what would you do if your patient had these things?

what are the good things about statins describe its beneficial timeline?

A

goal is a 50% reduction in LDL count if LDL responds and HDL doesnt you can add it

if patient <40 y/o or >75 y/o or LDL-C <70 risk-benefit profile done

clinical ASCVD <75 y/o high intensity if not tolerated moderate plus an additionl

LDL below 130

HDL >30 <80

34
Q

What is the rank of strength of the lipid medications?

A
35
Q

platelet cascade

A

factor 7 released from von vildebrand factor

36
Q

What are some adverse effects of the platelet inhibitors?

A
37
Q

What drugs interact w/ warfarin?

increase?

decrease

A
38
Q

What are the side effects of the reversal agents?

A
39
Q

What are the properties of the NOACs?

A

dont have to monitor short half life (requiring diligence to maintain antithrombotic event, not all have reversal agents

40
Q

what should warfarin only be used for over NOAC? what is it contraindicated in?

How do you dose warfarin properly?

A

mechanical heart valves or hemodynamically signifciant mitral stenosis;

contraindicated in renal disease

2-3 times as long to clot for: history of DVT, VTE prevention following surgery, mechanical aortic valve; rheumatic disease; stent placement; afib/flutter; cardioversion; mitral stenosis; cancer and PE

2.5-3.5 mechanical mitral valve

you want to dose it w/ a bridge a week before surgery to take someone off it

you can miss a dose

41
Q

What are the CHADS scores?

A

score of 2 or more high risk

score of 1 =moderate risk eval needed

42
Q

what do you do in the event of a venous thromboembolism?

A

•Initiate anticoagulation immediately upon diagnosis to prevent complications

▫Injectable (fondaparinux) or oral (apixaban, rivaroxaban) Factor Xainhibitors –OR –

▫Low molecular weight heparin (enoxaparin) – OR –

▫Unfractionated heparin

  • Long-term anticoagulation usually carried out with oral Factor Xaor direct thrombin inhibitors or with warfarin
  • Anticoagulation should last for 3-6 months unless this is a recurrent problem or permanent physiology in which case it would last longer (potentially lifelong)
43
Q

what are the normal selection of pharmacological agents postoperatively?

A
  • LMWH and injectiblefactor Xainhibitor for high-risk surgical patients (such as TKA, THA)
  • Low-Dose heparin: used with contraindication to LMWH (i.e. renal disease)
  • Warfarin used in a delayed setting unless bridging with enoxaparin carried out for immediate anticoagulation
  • ASA for orthopatients (THA, TKA) ineligible for other anticoagulation
  • Direct thrombin inhibitor, factor Xainhibitors not well studied, but rivaroxaban(following after knee and hip replacement) indicated following THA/TKA
44
Q

when do you use alteplase?

when do you treat DVT and PE?

A

▫PE:

–Persistent hypotension or shock break it

–Severe or worsening right ventricular dysfunction (“submassivePE”)

–Cardiopulmonary arrest due to PE

–Extensive clot burden (eg, large perfusion defects on ventilation/perfusion [V:Q] scan or extensive embolic burden on computed tomography)

–Free-floating right atrial or ventricular thrombus

–DVT:

▫Very rarely treated

–Systemic thrombolyticsare associated with decreased risk of post-thrombotic syndrome, increased risk of bleeding complications, and increased rate of complete clot lysis

–Only widely-accepted indication is for extensive ilio-femoral thrombosis with associated severely symptomatic limb swelling or limb-threatening ischemia
