Drugs and Blood pressure problems Flashcards
Patient comes in with high Bp what else do we want to know?
- has she ever had this before
- any other CVS issues
- diabetes, cholesteroel, stroke
- diet sodium intake, activity levels, alcohol, stress
- non-steroidals
What would we want to examine /investigaionts
- repeated measurements over the next month
- heart sounds
- cardiac exam
- test for organ damage - renal funciton, rpoteinuria, glucose ect.
Started on a bendrofluazide , what are potential adverse effects?
what if its od workign after a couple of weeks?
this is a thiazide diuretic
- can get hypokalemia
- dont give if atient has gout
- wait for later
Would doublign the dose beenfit her or not/
no, would just get side effects. Add an ace inhibitor
then add a calcium chanel blocker - side effects - dry cough
-can change to angiotensin 2 inhibitor which so dont get dry cough
Senario 2
- man with hypertension and angina
- allergy to aspirin
- give a calcium channel blocker (diltiazem) - sde efects - face flushign, oedema
- or give a beta blocker (metoprolol) - however, thsi is bad for asthma - bronchoconstriciton, also fatigue
what is a typical combonation for someonewith high cardiovascualr risk
-beta blocker
-anitplatelet agent
-satin
(ace inhibitor or calcium channel blocker if this is not workign)
what is paryoximal dyspnoea suggestive of?
-heart failure
3 main causes of heart attack
- Ischaemia (has had previous stroke)
- vascular heart disease
- hypertension
What to investigate for someone who has CCF, and AF, obese, hypertensionln, SOB
diagnose CCF - with echo, cxr, bnp
AF - ecg
Hypertension - test for end organ damage - ceratinne, protein uria
-also look for lipids and glucose - diabetes
What do we do in short term - give her fruzamine for fluid overload and an ace inhibitor to bring her back to normal fluid statis
Long term - beta blocker, statin, anticoagulant
weight reduction - exercis e
Lifestyle measures – Diet (Na+) – Exercise – Weight reduction • Pharmacological – Loop diuretic – ACE inhibitor – beta-blocker – spironolactone (frusemide 40mg) (cilazapril 5mg) (metoprolol)
What are secondary causes for hypertension (for young people)
Adrenal - mineralcorticoid - aldosterone increased (conns)
Phaeo - crushings RAS coartation of the aorta alchol recreation drugs - amphetamines, cocaine - good social history
Licroice - active ingredeint - inhibits an enzyme - that breaks down cortisol increases aldosterone
how can we investigate these?
Obese (Cushingoid) • BP – appropriate size cuff • BMI • R-F delay (palpable femorals) • Abdominal bruit • Renal masses • Fundi
• MR – renal arteries/coarctation • Plasma metanephrines • Aldosterone / renin ratio • U + E, Glucose • Urine dipstick • ECG • CXR -echo
why is she hypokalemic ?
- because she is taking diuretic
- aslo could be due to icnrease aldosterone (aldoseteonr producing tumour)
- if get too much aldosterone, then get renin feedback so decreases renin
- and then get decrease potassium
-could do an MRI to see if there is a tumour
