Observational
Dyspnea is strongly associated with angina pectoris in ischemic heart disease and frequently precedes the onset of chest pain, serving as an important prognostic symptom.
Hagman et al. (1981) conducted an observational in Ischemic heart disease and angina pectoris. Dyspnea vs. No dyspnea was evaluated on Occurrence of angina pectoris. Dyspnea was reported in 21% of the general population and 70% of the angina population, and was present at baseline in 36% of men who subsequently developed angina pectoris over 4 years.
