what is pericarditis
inflammation of the pericardium (usually serous pericardium) or pericardial fluid
what is pericarditis caused by
usually viral infection but can also be from systemic diseases or trauma
what are the signs and symptoms of pericarditis
- Sharp Retrosternal chest pain (may radiate to back or L trap)
- Increases with cough or deep breathing
- decreases with sitting upright and leaning forward
diagnostic tool for pericarditis
auscultation - friction rub
medical work up for pericarditis
increases WBC, Sed rate, C-reactive protein, and troponins initially but will not continue to increase.
management for pericarditis
acute (not lasting longer then 3 weeks)
- rest, pain medication with anti-inflammatory drugs or steroids)
Chronic
- IV antibiotics or pericardial drainage
what is constrictive pericarditis
chronic pericarditis or pericardial effusion that results in the thickening and scarring of the pericardium
symptoms of Constrictive Pericarditis
- dyspnea
- LE and abdominal swelling
- dizziness or syncope
- retrosternal chest pain
- Jugular venus distention
what is pericardial effusion
accumulation of fluid in the pericardial space
symptoms of pericardial effusion
fullness in chest, cough, hoarseness, dysphagia
medial work up for pericardial effusion
- muffles heart and lung sounds
- dullness to percussion of left lung at angle of the scapula
- enlarged cardiac silhouette
- echocardiography
Cardiac Temponade
accumulation of fluid in the pericardial space that exerts pressure on the heart
symptoms of Cardiac Tamponade
becks triad (Hypotension, JVD with pulsus paradoxus, decreased heart sounds)
treatment for cardiac tamponade
cut a cardiac window or pericardial window
Endocarditis
Infection of the endocardium from bacteria or fungi
cause of endocarditis
bacteria travels from another part of the body
signs and symptoms of endocarditis
- flu like symptoms, pain with breathing, SOB, swelling, fever
- may hear mitral valve regurgitation on ausculation
people at highest risk for endocarditis
- artificial hear valves

- Possible valve replacement
Myocarditis (inflammatory cardiomyopathy)
infection or inflammation of the heart wall/muscle
what is myocarditis caused by
viral or bacterial infection (streptococcal most common). in rare cases; drug induced
what does myocarditis affect
both pump and electrical conduction
signs and symptoms of myocarditis
weakens pump action: SOB, diffuse chest pain, fatigue, edema) and arrhythmias
if myocarditis is untreated what can it lead to
- heart failure due to damaged cardiac muscle and decreased pump function
- MI or CVA due to pooling of blood in ventricles
- Arrhythmia (possible sudden cardiac death)
Cardiovascular disease definition
is the umbrella term for all types of diseases that affect the heart or blood vessels, including coronary artery disease, which can cause heart attacks, stroke, heart failure, and peripheral artery disease
hypertension
blood pressure readings that are consistently over established guidelines
coronary artery disesase
a buildup of atherosclerotic plaque formation in the vessel lumen that leads to impairment in blood flow and O2 delivery to the myocardium

what are some things that HTN can lead to
-heart failure
- myocardial ischemia and infarction
- aortic aneurysm and dissection
- stroke

- lower physical and emotional threshold
- chest pain at rest or not relieved by rest
- change in anginal pattern
Unstable Angina PT implications
- get physician clearance
- know meds
- lifestyle modifications
- self monitoring of symptoms
- extend warm up and cool down

- no HIIT
Ischemic heart diseases
stable and unstable angina
myocardial infarction (MI) most common cause
- atherosclerotic plaque rupture in an already blocked artery
