Cardiac and Medical Emergency Symptoms

Cardiac Symptoms Requiring Emergency Response

The American Heart Association recommends calling 9-1-1 immediately if chest discomfort lasts more than 5 minutes, or if severe shortness of breath, syncope, or symptoms accompanied by cold sweats, nausea, vomiting, or a sense of impending doom occur 1, 2
Chest pain or discomfort lasting >20 minutes at rest requires immediate emergency transport by ambulance, as recommended by the American College of Cardiology 1, 2
The European Society of Cardiology states that chest symptoms interrupting normal daily activities indicate a potentially serious condition 3, 4, 5
Symptoms may present variably as chest pain, oppression, dyspnea, heavy chest, or even slight discomfort—all warrant urgent evaluation if persistent, according to the European Heart Journal 3, 4, 5
Radiation of discomfort to the arm, jaw, neck, or back increases concern for acute coronary syndrome, as noted by the European Heart Journal 3, 4, 5
The American College of Cardiology recommends taking one nitroglycerin dose if previously prescribed for known heart disease or cardiac risk factors with chest discomfort, and calling 9-1-1 immediately if symptoms are unimproved or worsening after 5 minutes 1, 2
For patients without known cardiac disease experiencing new chest symptoms, the American Heart Association recommends calling 9-1-1 if symptoms persist beyond 5 minutes 1, 2
While waiting for emergency services, the American College of Cardiology suggests chewing 162-325 mg of non-enteric-coated aspirin unless allergic 1

The European Heart Journal warns against waiting for symptoms to disappear, as symptom resolution is a poor indicator of risk, and against driving oneself or having family drive with suspected cardiac symptoms—instead, call 9-1-1 for ambulance transport 1, 3, 4, 5
The American College of Cardiology notes that women and elderly patients frequently present atypically with dyspnea, fatigue, or nausea rather than classic chest pain, and recommends not taking more than one nitroglycerin before calling 9-1-1 if symptoms are unimproved or worsening 1, 2
