Evaluation of Sudden Chest Pain

Chest Pain Characteristics

The American College of Cardiology recommends assessing the nature of chest pain, including descriptors like pressure, squeezing, and heaviness, which are more suggestive of ischemic cardiac pain 1, 2
The American College of Cardiology suggests determining the onset and duration of pain, as pain that builds gradually is typical of angina, while sudden onset is concerning for aortic dissection 1, 2
The American Heart Association recommends identifying the location and radiation of pain, as pain radiating to the back may suggest aortic dissection 1, 3
The American College of Cardiology advises asking about the severity of pain, including if it is the "worst pain ever", which is concerning for aortic dissection, especially in hypertensive patients 1, 3
The American College of Cardiology suggests determining if pain is triggered by exertion, emotional stress, or occurs at rest 1
The American College of Cardiology recommends asking if rest, nitroglycerin, or position changes affect the pain 1

The European Society of Cardiology notes that diaphoresis, nausea, vomiting, and shortness of breath are common associated symptoms of cardiac chest pain 2, 4, 5, 6
The American College of Cardiology recommends considering syncope or presyncope as a symptom that may indicate severe cardiac disease or pulmonary embolism 2, 6
The American Heart Association suggests that palpitations may indicate arrhythmia as a cause of chest pain 6
The American College of Cardiology notes that fever may indicate infectious causes like pneumonia or pericarditis 6

The American College of Cardiology recommends considering accompanying symptoms that are more common in women with acute coronary syndrome (ACS), such as nausea, vomiting, dyspnea, back/neck/jaw pain 2, 5, 6
The American Heart Association suggests that elderly patients (≥75 years) with shortness of breath, syncope, acute delirium, or an unexplained fall should be considered for ACS 2, 6
The American Diabetes Association recommends being alert for atypical presentations of chest pain in diabetic patients due to autonomic dysfunction 6

The American College of Cardiology recommends assessing cardiovascular risk factors, including history of coronary artery disease, hypertension, diabetes, smoking, and family history of premature CAD 1, 2
The American Heart Association suggests considering previous cardiac events, such as prior myocardial infarction, angina, or revascularization procedures 1, 2
The American College of Cardiology notes that aortic risk factors, including history of hypertension, connective tissue disorders, bicuspid aortic valve, or known aortic dilation, should be assessed 1, 3

The American College of Cardiology recommends assessing vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation 6
The American Heart Association suggests performing a cardiovascular examination, including heart sounds and signs of heart failure 6
The American College of Cardiology notes that chest wall tenderness and pulse differentials between extremities should be assessed 6

The American College of Cardiology recommends considering ripping chest pain with radiation to the back, especially in hypertensive patients or those with known aortic disease, as a red flag requiring immediate action 1, 3
The American Heart Association suggests that severe pain with diaphoresis, tachypnea, tachycardia, or hypotension requires immediate attention 6
The American College of Cardiology notes that new-onset left bundle branch block or ST-segment changes on ECG, as well as pain associated with syncope, severe dyspnea, or hemodynamic instability, are red flags requiring immediate action 2, 6

The American College of Cardiology recommends avoiding underdiagnosis of women with chest pain, who are at higher risk for underdiagnosis and should always be evaluated for potential cardiac causes 2, 6
The American Heart Association suggests avoiding dismissal of atypical presentations in elderly patients, who may present with shortness of breath, confusion, or falls rather than classic chest pain 2, 6
The American College of Cardiology notes that relying solely on pain intensity is not reliable for predicting the seriousness of the underlying condition, and that delayed ECG and premature diagnostic closure should be avoided 2, 4, 5
