Q

Ischemic Heart Problems

A

Atherosclerosis develops in the arteries supplying the myocardium ARTERY BLOCKAGE

  • Decreased tissue perfusion
  • ENDOTHELIAL DYSFUNTION
  • Heart must work harder

Q

Main symptom of CAD

A

Angina

  • May be asymptomatic
  • Eventually, as coronary arteries narrow, the decreased blood flow may cause chest pain (angina)

Q

Anytime someone comes into ER for Chest pain

A

It’s important to rule out HEART being cause before exploring non-cardiac issues

17
Q

Chest Pain: Cardiac

A
  • “pressure or tightness”
  • Diffuse, poorly localized
  • Associated with physical exertion or other stress”
  • Relieved with rest, within minutes
  • Prolonged symptoms may represent an acute coronary syndrome (MI)
18
Q

Chest Pain: Non-Cardiac

A
  • Sharp or stabbing
  • Focal, well localized
  • May be positional, spontaneous at rest
  • No predictable relation to physical exertion
  • May last from seconds to even days at a time
19
Q

Atypical Angina: Women

A

Discomfort

  • hot or burning
  • Tenderness

Location: Not always in chest

Other Symptoms

  • Indigestion
  • Heartburn
  • Nausea
  • Fatigue/weakness
  • Lightheadedness
  • Dyspnea
20
Q

Angina Pectoris and pain associated with Myocardial Infarction (heart attack symtoms)

A
  • Chest pain not brought on by exertion
  • Chest pain may radiate to other areas (arms, jaw, shoulders, back)
  • Pain not relieved in 2-5 minutes
  • Accompanies by SOA, N/V/ diaphoresis
  • Risk for MI greatly increases
21
Q

What do we do with stable angina?

A

Educations: rest and relaxation

  • Decreasing Demand
  • Nitrates
  • Prevent/treat further atherosclerosis
  • TEACH ABOUT MI’s
22
Q

Angina

A

If you sit down for about 5 minutes and your chest pain doesn’t get better CALL 911
