how to differentiate between myocarditis and pericarditis
Myocarditis is more likely to show a focal ECG changes
> also more likely to show acute congestive HF signs / Left ventricular failure signs
pericarditis is widespread
why does myocarditis present with left ventricular dysfunction signs?
inflammation reducing contractile strength of the heart
causes of myocarditis?
viral : coxsackie
bacterial : diphtheria, clostridia
fungal : toxoplasmosis
mx of angina?
First line : beta blocker
or if not tolerated / contraindicated
first line : CCB NDHP - verapamil / diltiazem
2nd line: Beta blocker and Dihydropyridine CCB - amlodipine / nifedipine
3rd line - add 3rd drug but awaiting PCI / CABG
other angina medications?
a long-acting nitrate
ivabradine
nicorandil

Stage III HF
pain on less vigorous studd
like daily activities impacted
but no pain at rest
stage 1 HF?
Stage I - No limitation on ordinary physical activity (incorrect)
PKD is associated with what valve abnormality?
mitral valve prolapse
management of cardiac tamponade?
pericardiocentesis
when should you take statins?
at night- increases efficacy
beta blockers licensed for HF?
bisoprolol, carvedilol, and nebivolol.
2nd line HF?
with reduced ejection fraction
beta blocker, ACEi, + mineralocorticioid receptor antagonist
> be wary of hyperkalaemia
role of SGLT-2 drugs inhibitors
SGLT-2 inhibitors
reduce glucose reabsorption and increase urinary glucose excretion
dapagliflozin
sacubitril-valsartan
criteria?
3rd line
left ventricular fraction < 35%
reduced ejection fraction who are symptomatic on ACE inhibitors or ARBs
initiated after a washout period
role of digoxin
very helpful w symptoms
t is strongly indicated if there is coexistent atrial fibrillation
major bleed and on warfarin mx?
stop warfarin
IV vitamin K 5mg and prothrombin concentrate complex
Ivabradine is used in?
MOA?
S/E?
inhibition of IF channels
I current
F = funny
mixed na+/K+ in heart like Sinoatrial node
angina management
transient luminous phenomenon
what is the MOA of ivabradine?
inhibits channels
= delay in depolarisation
= slows down heart rate

> 135/85 on
ABPM / HBPM
when to start anti hypertensives?
<80
+ target organ damage
CVD disease
renal disease
