Diagnosis of Dilated Cardiomyopathy
Exclude other causes of contractile failure (HTN, CAD, valvular disease).
Test for specific etiologies ?Percutaneous endomyocardial biopsy
Extremities: Mild edema of both feet and ankles.
Dilated Cardiomyopathy
Dilation of one or both ventricles Globally impaired ventricular systolic
function: both ventricles or predominantly the left ventricle. Isolated RV cardiomyopathy is rare.

Physical Exam
BP 105/70, P 98 regular, T 98.6, RR 20 Carotids are low volume with normal upstroke. JVP elevated: 10 cm above the sternal angle. Lungs: Bibasilar rales. Heart: PMI diffuse, palpable at the anterior axillary line.
Dynamic murmur of HOCM
• Smaller LV volume brings septum closer to anterior MV leaflet: more obstruction and louder murmur.

deficit that has a sudden onset, lasts more than 24 hours, and results from cerebrovascular disease.
A stroke occurs when there is a disruption
of blood flow to a region of the brain.
Dysphasia: difficulty in speaking and putting words into the correTATIONS
A stroke is usually characterized by the sudden onset of focal neurological impairment.
About one-fourth of strokes are hemorrhagic, resulting from hypertensive vascular disease (which causes an intracerebral hemorrhage), a ruptured aneurysm, or an arteriovenous malformation.
Risk factors for stroke include smoking, hypertension, obesity, cardiac disease, hypercholesterolemia, diabetes, and use of birth control pills.
Prevention efforts focus on lifestyle changes that can modify risk factors.

CVD
Question: What is the relative amount of CVD in death rates in women and men?
- Migration: Ni-Hon-San Study: Japanese living in Japan had the lowest rates of CHD and cholesterol levels, those living in Hawaii had intermediate rates for both, those living in San Francisco had the highest rates for both
- Women: special case (WHO, 2004)
a., Higher risk in women than men (smoking, high triglyceride levels)
b., Higher prevalence of certain risk factors in women (diabetes mellitus, depression)
c., Gender-specific risk factors (risks for women only) (oral contraceptives, hormone replacement therapy, polycystic ovary syndrome)
Question: What is the relative amount of CVD in death rates in different ethnic groups?
Question: What is the relative amount of CVD in death rates in different age groups?
- Early lesions of blood vessel, atherosclerotic plaques: around 20 years - adult lifestyle patterns usually start in childhood and youth (smoking, dietary habits, sporting behavior, etc.)
