Description

Angina occurs when the heart must do extra work but does not receive enough oxygen for its needs because a coronary artery is narrowed due to arteriosclerosis. angina may occur not only in the case of physical exertion but also during an episode of mental stress or the digestion of a large meal. Angina pain generally disappears quickly once the activity has stopped or with nitroglycerin.

Someone has stable angina when the angina pain occurs and can be reproduced during specific activities and remains of short duration.

Unstable angina , which is also called acute coronary syndrome, refers to prolonged pain that generally occurs when patients are at rest and that can be a sign of myocardial infarction (heart attack). These symptoms are described in the Acute Coronary Syndrome section.

Protection and prevention

It is important for angina patients to work with their doctors on the risk factors listed above. Quitting smoking, reaching a healthy weight, eating a healthy diet and following an adapted exercise program are part of treatment, which also includes taking medication to treat high blood pressure or diabetes. These recommendations are applicable for people who want to avoid developing coronary atherosclerosis (primary prevention) and for people who have already been diagnosed with this condition (secondary prevention).

Treatment

L’angine stable est habituellement traitée par la prise de médicaments qui diminuent le travail du coeur et dilatent les artères. Un médicament pour réduire les risques de caillots dans le sang (aspirine ou autre) est de plus indiqué de même qu’un médicament visant à diminuer les effets nocifs du cholestérol sur la paroi des artères. Si ces mesures ne suffisent pas ou si les tests démontrent une atteinte particulièrement sévère, des interventions spécialisées peuvent être effectuées soit par cathétérisme soit par chirurgie:

  • une angioplastie avec ou sans l’installation d’un tuteur (stent)
  • un pontage coronarien
