signs snd symptoms
1. chest pain
  1. other causes
  2. Heart problems
    1. Lung problems
      1. Gastrointestinal Problems
        Bone, Muscle, or Nerve Problems
        Rib problems, muscle strain, shingles
        GERD, peptic ulcers
      2. Pneumonia, pleuritis, pneumothorax
    2. CAD , MI , myocarditis
2. exertional dyspnea, angina and syncope
risk factors
1. old age
2. congenital heart disease
3. family and medical history
4. male gender
5. obesity and physical inactivity
prevention
causes
1. rheumatic fever
  1. Group A strep pharyngitis
    1. Morphology: Aschoff bodies and Anitschkow cells
      1. PANCARDITIS
2. wear and tear
physiology of the heart
1. cardiac cycle
  1. sounds
    1. normal
      1. lub-dub
    2. murmurs
      1. causes
        due to a narrowing (stenosis) of the mitral or tricuspid valves, or regurgitation of the aortic or pulmonary valves.
        backward blood flow into one of the chambers of the heart
        due to blood flow through a narrowed vessel or irregular valve
      2. types
        systolic
        diastolic
        continuous
        Thrill is defined as a palpable murmur that correlates with zones of maximum intensity of auscultated sounds.
  2. series of events that take place in the heart over the duration of a single heart beat
2. cardiac output
  1. controlled by
  2. stroke volume
    1. affected by
      1. afterload
    2. preload
    3. contractility
  3. heart rate
3. blood pressure
  1. hypotension & consequences
    1. dizziness
    2. fatigue
    3. blurred vision
anatomy of the heart
2. heart valves
  1. aortic valve
    2. Three cusps, lies between the left ventricle and the aorta
    3. During ventricular systole, when pressure in the ventricle is greater than in the aorta, the aortic valve opens
pathogenesis
treatment
1. Lifestyle changes
  1. Balloon valvuloplasty
2. Aortic valve repair
  1. Aortic valve replacement
investigations
1. angiography
2. Blood pressure monitoring
3. Blood tests
4. Echocardiogram (echo) tests
  1. Electrocardiograph (ECG) tests
