-"heart muscle disease" is the measurable deterioration for any reason of the ability of the myocardium (the heart muscle) to contract, usually leading to heart failure
-Symptoms & Signs :
.dyspnea
.peripheral edema
.irregular heart rate
.sudden cardiac death
-Types :
1.Dilated Cardiomyopathy DCM
-Is a condition in which the heart becomes enlarged and cannot pump blood efficiently (M.C form)
-Causes heart failure & arrhythmia
2.Hypertrophic Cardiomyopathy HCM
-Is a primary disease of the myocardium (the muscle of the heart) in which a portion of the myocardium is hypertrophied (thickened) without any obvious cause, creating functional impairment of the cardiac muscle
-Familial (autosomal dominant)
-M.C.C of sudden death in young athletes
3.Restrictive Cardiomyopathy RCM
-Is a form of cardiomyopathy in which the walls are rigid,and the heart is restricted from stretching and filling with blood properly
-M.C.C is amyloidosis
4.Constrictive Pericarditis
-Is a medical condition characterized by a thickened, fibrotic pericardium, limiting the hearts ability to function normally
-M.C.C is idiopathic
-Other Causes :
.TB
.sarcoidosis
.Rt side heart failure
.lower limbs edema
.ascities
.hepatomegaly
.chronoc renal failure
.post-myocardial infection
.post-viral pericarditis
.chronic pericarditis
.heart surgery
+Contraindication for thrombolytic therapy :
.stroke (within 2 months)
.HTN (uncontrolled)
.surgery (within 6 days)
.bleeding disorder
.non-STEMI
.post MI (>12hrs)
**End Diastolic Volume EDV
-Is the volume of blood in the right and/or left ventricle at end load or filling in (diastole) or the amount of blood in the ventricles just before systole
-Ejection fraction EF = stroke volume EDV (stroke volume=70cc)
