Dyspnea could often predict worse survival for heart attack patients as compared to chest pain, suggests the latest research findings presented at ESC Acute Cardiovascular Care 2022. The research, conducted by Dr Paulo Mederiros and his colleagues from Braga Hospital, Portugal, found that chest pain, dyspnea, tiredness, high blood pressure, diabetes, kidney and lung diseases were the most common symptoms in heart attack patients, which do not necessarily cause poorer outcomes, but reportedly is warning signs of greater risk. However,  the research that analysed 4,726 patients found that 94 percent of patients with chest pain as the predominant symptom survived, whereas only 76 percent of the patients with dyspnea or fatigue survived.
