Types of cardiomyopathy
dilated, hypertrophic, restrictive
dilated cardiomyopathy
disease of the heart muscle that causes the heart to become enlarged and to pump less strongly
mostly in elderly population
hypertrophic cardiomyopathy
heart muscle becomes enlarged and blocks blood flow
Affects young athletes
restrictive cardiomyopathy
heart muscle hardens, restricting the expansion of the heart, thus limiting the amount of blood it can pump to the rest of the body
most rare
Symptoms of cardiomyopathy
Breathlessness with exertion even at rest, swelling of the legs, ankles and feet, bloating of the abdomen due to fluid buildup, fatigue, irregular heartbeat, dizziness, lightheadedness and fainting.
cardiomyopathy medications

treatment for mitral stenosis
patient education new pacemaker
--Keep their arm down for the first month
--follow up with cardiology closely,
--take your medications
--keep the site dry and clean
when to seek care if you have a pacemaker
· Dizzy or lightheaded
· Alarm or feel buzzing from pacemaker
· It heart rhythm is not at the paced level

-- viral
-- fungal
Pericarditis S/S
chest pain worse when lying down, cough, fever, anxiety, FRICTION RUB
PVC (Premature Ventricular Contraction)
Big wide QRS
looks bizarre with what appears to be an extra QRS
Can lead to VTach can be dangerous
Causes of PVCs
--Digoxin toxicity, hypoxia, hypokalemia, fever, acidosis, exercise
--can be caused by caffeine, alcohol, hypertension and thyroid disease
-- check electrolytes especially potassium
PVC symptoms
palpitations or skipped heart beat
PVCs treatment
-None is asymptomatic
-If symptomatic: beta blockers or ablation
-- lifestyle changes
renal transplant
surgical implantation of a donor kidney into a patient with inadequate renal function
Signs of renal transplant rejection
Temperature higher than 100
Pain or tenderness over grafted kidney
2-3 lb wt gain in 24 hours
Edema
HTN
Malaise
Elevated BUN and creatinine
Deceased creatinine clearance
Elevated WBC
Rejection indicated by ultrasound or biopsy
R-region and radiation (where is it, where does it go?)
S-signs and symptoms (SOB, diaphoresis)
T-timing and responses to treatment (when start; better/worse)
Treatment for STEMI
--known as MONA (morphine, oxygen, nitroglycerin, and aspirin).
-- Remember in right ventricular infarctions do not use
nitroglycerin as it decreases preload.
-- anticoagulation such as heparin or enoxaparin.
-- antiplatelet therapy the standard of care is dual platelet therapy; such as, aspirin and clopidogrel.
-- reperfusion therapy
--The goal is door to balloon time within 90 minutes.
