Repeat test but use pharmacological stress test
A pt with chronic angina now comes in with increased frequency. already on ASA and nitrate.
pt still has chest pain. HR 80
pt still has chest pain but HR is now 55
Add beta blocker
Increase the dose of beta-blocker
Angiogram with possible PCI

What is this called, and how to diagnose it

what’s the etiology of the chest pain
Ischemia
What is Wellens syndrome on EKG
Only deep T-wave inversions in leads V1-V4

EKG shows deep T wave inversions in leads V1 through V4.
w.t.d
Angiogram right away.
don’t need to wait for the stress test

What’s the diagnosis and what’s the treatment
Postprandial ischemia
Cardiac cath and have him eat small frequent meals

how to treat
PCI
Benzo, nitrates, and ASA. In that order
Use CCB to prevent CP in the future

afterwards, CP and ST elevation were resolved. Trop tripled.
w.t.d

take this person straight to cath lab
Pt with CP and ST elevation get tPA and 2 hours later BP drops and the pt is SOB.
w.t.d
PCI NOT IABP

w.t.d
PCI and if PCI isn’t available —> tPA
pt gets tPA for STEMI what needs to be done next
PCI AFTER 2 hours
BUT if the patient starts to become unstable—> PCI NOW and don’t wait the 2 hours
pt is admitted with MI; 3 days later, presents with chest pain relieved with NTG. w.t.d
Cath

- After load reduction (ACE or ARNI)
- Stop smoking
- Statin
- ICD 40 days after MI
- ICD 90 days after PCI
- Cardiac rehab
PCI, CABG, or statin. Which one improves LONG-TERM survival
Statin
What is the sequence of events for the management of ACS.
- ASA
- NTG
- Beta-blockers
- Atorvastatin
- UFH
- Ticagrelor
- PCI
pt with unstable angina with CKD. has already received ASA, BB, and statin.
Unfractionated heparin
NOT LMWH
pt with MI has acute MR
Papillary muscle rupture
pt with MI has acute VSD
Septal wall rupture
Pt with MI has signs of tamponade
Free wall rupture
Pt presents with CP. EKG reveals an MI and is treated with tPA, heparin, nitrates, BB, and ACE. Within 24 hours, pt develops NSVT. w.t.d
Just observe.
What the mechanism of reperfusion arrhythmias
accumulated calcium causing a change in cardiac frequency
Pt presents with CP. EKG reveals an MI and is treated with tPA, heparin, nitrates, BB, and ACE. Within 24 hours, pt develops sustained VT and is unstable. w.t.d
Cardiovert QRS is distinct or just defib if QRS or T is not seen.
Pt presents with CP. EKG reveals an MI and is treated with tPA, heparin, nitrates, BB, and ACE. Within 24 hours, pt develops sustained VT and is stable. w.t.d
give amio or lidocaine
If post-MI arrhythmias are less than 48 hours, what is the cause
ischemia
If post-MI arrhythmias are greater than 48 hours, what is the cause?
Scare tissue. pt will need ICD
Pt with ICD post-MI has 2 discharges in 2 months
add amio
Pt with ICD and amio post-MI is still having discharges
Radiofrep cath ablation
What patients need CRT with ICD
LBBB or QRS prolongation
What pts need CRT and ICD placed at the same time
LBBB or QRS prolongation AND EF less than or equal to 35%
What would you see on EKG 2-3 weeks after post-MI pericarditis
Deep T waves inversions
pt has CABG or AVR 4 years ago. now has SOB for the last 3-4 months. JVD, hepatomegaly, and pedal edema. EKG and CxR look normal. whats the Dx
Pericarditis
Pt presents with SOB on exertion with BMI of 40 and JVD of 14. BNP is only 160
IV Lasix
falsely low with obesity
This is called a type 2 error.
You start CHF patients on ACE or ARNI. Now has Scr that jumped from 1.1–>2, and K jumped from 4–>5.6. w.t.d
D/C ACE or ARNI and start hydralazine and nitrates
Pt on oral Lasix now has severe pitting edema and JVD of 12. w.t.d
Switch to IV Lasix and maximize the ACE. There is likely a lack of gut absorption.
Pt is D/C from the hospital for CHF exacerbation. What’s the next best step in management?
Setting up follow-up visit within one week.
Pt on spironolactone for six months and now has a left breast enlargement. w.t.d
Biopsy
Pt on spironolactone for six months and now has a bilateral breast enlargement. w.t.d
D/C spironolactone and start eplerenone
CHF patient on Lasix 60mg daily. All other HF meds are maxed out. The echo shows EF of 35% and EKG shows QRS 0.15 secs and LBBB
Start metolazone 30min before Lasix. This is part of GDMT. Don’t start ICD with CRT just yet
CHF patient on Lasix 60mg daily. All other HF meds are maxed out. The echo shows EF of 35%, and EKG shows QRS 0.15 secs and LBBB.
You start metolazone 30min before Lasix. 3 months later nothing has changed
Start ICD and CRT
EF less than 35% –> start ICD
EF less than 35% and LBBB or ORS great than 15 sec –> ICD and CRT at the same time
what drugs DONT improve survival in heart failure
Digoxin
CCB
Lasix
How do you switch from ACE to ARNI
D/C ACE and wait 36 hours for a wash-out period, and then start ARNI.
The only exception to this rule would be if the patient is on candesartan. You can switch to ANRI after 24 hours
You start ACE and pt has syncope. w.t.d
Continue ACE.
first dose syncope
You start ACE and pt develops angioedema
Switch to ARB
What sort of kidney issues are associated with ACE
Decreased constriction on efferent arterioles. This can cause renal failure in marginal patients
Can ACE cause neutropenia
Yes
What drugs should you not use in heart failure
NSAIDS Glitazone CCB cilostazol Metformin in advanced disease
ACE and ARB combo has shown what
Less proteinuria and poorer renal outcomes
