Apart from dyspnea, there are some other “typical” and “early” signs that could warn that something is wrong.
Dr Xu said: “The majority of patients experience somewhat typical symptoms, such as radiating chest pain, heaviness or discomfort, heart palpitations, cold sweats, and shortness of breath.
“Others – women more so than men – will experience some atypical symptoms as well, which may include fatigue, a general sense of unease, vague discomfort, back or abdominal pain and declining stamina.
“Both types of symptoms can be experienced months before an actual heart attack occurs.”
