Overview
Reduced LV function, number and location of stenoses, workload in METs calculated using Duke score are the strongest predictors of survival in patients with chronic stable angina.
Prognosis
Mortality
- The estimated annual mortality rate in patients with chronic stable angina ranges from 0.9% - 1.4%[1][2][3] with an annual incidence of non-fatal MI between 0.5%[4] and 2.6%.[5]
- The Framingham Heart Study[6][7] revealed the 2-year incidence rates of non-fatal MI and coronary heart disease death for men and women who initially presented with stable angina was 14.3% MI and 5.5% CAD death in men, and 6.2% MI and 3.8% CAD death in women.
- Relative risk based on anginal characteristics in elderly associated with no comorbidities:[8]
Characteristic | 1-yr Mortality Rate (%) |
Non anginal pain | 0.4 |
Atypical angina | 0.8 |
Stable angina | 1.3 |
Progressive | 1.5 |
Unstable | 1.7 |
Factors that Affect Long Term Prognosis in Patients with Chronic Stable Angina
- Reduced LV function (reduced ejection fraction; LV hypertrophy) remains the strongest predictor of survival in patients with chronic stable angina.[8]
- Location of stenosis (proximal stenosis involving the left main and proximal left anterior descending artery (LAD), are associated with poor outcomes and increased risk of ischemic events).
- Number of stenoses (patients with three-vessel disease have a higher mortality rate in comparison to patients with single vessel disease).
Extent of CAD | Prognostic Weight (0-100) | 5-year Mortality Rate (%) |
(assuming medical treatment only) | ||
1-vessel disease, 75% | 23 | 7 |
>1-vessel disease, 50-74% | 23 | 7 |
1-vessel disease, ≥ 95% | 32 | 9 |
2-vessel disease | 37 | 12 |
2-vessel disease, both ≥ 95% | 42 | 14 |
1-vessel disease, ≥ 95% proximal LAD | 48 | 17 |
2-vessel disease, ≥ 95% LAD | 48 | 17 |
2-vessel disease, ≥ 95% proximal LAD | 56 | 21 |
3-vessel disease | 56 | 21 |
3-vessel disease, ≥ 95% in at least 1 | 63 | 27 |
3-vessel disease, 75% proximal LAD | 67 | 33 |
3-vessel disease, ≥ 95% proximal LAD | 74 | 41 |
- Associated risk factors[9] that contribute to poor outcomes are:
Duke Score (Exercise Treadmill Test)[10]
- Workload in METs assessed using the DUKE Score is an important factor in estimating the prognosis of patients with chronic stable angina.
- Duke score = [(exercise duration in minutes) - (5 x ST segment deviation in millimeters) - (4 x treadmill angina index)]
- Angina index:
- 0 for no angina,
- 1 for angina, and
- 2 if angina is the reason for stopping the test.
CAD risk probability (DTS) | 4-year survival | Annual mortality |
Low probability (more than 5 DTS) | 99% | 0.25% |
Moderate probability (-10 to 4 DTS) | 95% | 1.25% |
High probability (less than -10 DTS) | 79% | 5% |

Class I |
"1. CABG for significant left main CAD or its equivalent (i.e. severe stenosis of ostial/proximal segment of left descending and circumflex coronary arteries). (Level of Evidence: A)" |
"2. CABG for significant proximal stenosis of three major vessels, particularly in those patients with abnormal LV function or with early or extensive reversible ischaemia on functional testing. (Level of Evidence: A)" |
"3. CABG for one- or two-vessel disease with high-grade stenosis of proximal LAD with reversible ischaemia on non-invasive testing. (Level of Evidence: A)" |
"4. CABG for significant disease with impaired LV function and viability demonstrated by non-invasive testing. (Level of Evidence: B)" |
Class IIa |
"1. CABG for one- or two-vessel CAD without significant proximal LAD stenosis in patients who have survived sudden cardiac death or sustained ventricular tachycardia. (Level of Evidence: B)" |
"2. CABG for significant three-vessel disease in diabetics with reversible ischaemia on functional testing. (Level of Evidence: C)" |
"3. PCI or CABG for patients with reversible ischaemia on functional testing and evidence of frequent episodes of ischaemia during daily activities. (Level of Evidence: C)" |
