Prognosis
The prognosis of a disease is the likely outcome. It can be improved by treatment and worsened by additional risk factors.
The main prognostic markers in both stable and unstable angina include the number of vessels affected, location of affection, and whether it affected the heart’s contractile force -also known as left ventricular function.
Generally speaking, unstable angina has a much worse prognosis than stable angina and a higher risk of myocardial infarction progression. One of the important prognostic indicators besides treatment, is smoking.
It was observed that patients who continue to smoke after their diagnosis have an increased risk of about 50% of developing myocardial infarction than those who cease smoking—appropriate early interventions, whether medically or surgically, have a significant impact on patients’ survival as well.
