Key Clinical Updates in Chest Pain

One trial of patients hospitalized with mild hemoptysis compared tranexamic acid with saline placebo; within 5 days of hospital admission, hemoptysis resolved in more patients treated with tranexamic acid than in those receiving a saline placebo.

In African-American patients with average cardiovascular risk, HEART score is a better predictive tool for 6-week major adverse cardiac events when compared to TIMI score.

In the PROMISE trial, women had higher rates of normal noninvasive testing compared with men, but those women with abnormalities were less likely to be referred for catheterization or to receive statin therapy.


  • Pain onset, character, location/size, duration, periodicity, and exacerbators; shortness of breath.

  • Vital signs; chest and cardiac examinations.

  • Electrocardiography and biomarkers of myocardial necrosis in selected patients.


Chest pain (or chest discomfort) is a common symptom that can occur as a result of cardiovascular, pulmonary, pleural, or musculoskeletal disease; esophageal or other gastrointestinal disorders (including a foreign body, eg, a fish bone); herpes zoster; cocaine use; or anxiety states. The frequency and distribution of life-threatening causes of chest pain, such as acute coronary syndrome (ACS), pericarditis, aortic dissection, vasospastic angina, pulmonary embolism, pneumonia, and esophageal perforation, vary substantially between clinical settings. In the Netherlands and Belgium, chest pain was the reason for consulting the general practitioner in 1.26% of all cases. In 8.4% of patients with chest pain, life-threatening underlying causes were identified. Systemic lupus erythematosus, rheumatoid arthritis, reduced estimated glomerular filtration rate, and HIV infection are conditions that confer a strong risk of coronary artery disease. Precocious ACS may represent acute thrombosis independent of underlying atherosclerotic disease. In patients aged 35 years or younger, risk factors for ACS are obesity, hyperlipidemia, and smoking.

Chest pain characteristics that can lead to early diagnosis of acute myocardial infarction do not differ in frequency or strength of association between men and women. Because pulmonary embolism can present with a wide variety of symptoms, consideration of the diagnosis and rigorous risk factor assessment for venous thromboembolism (VTE) is critical. Classic VTE risk factors include cancer, trauma, recent surgery, prolonged immobilization, pregnancy, oral contraceptives, and family history and prior history of VTE. Other conditions associated with increased risk of pulmonary embolism include HF and COPD. Sickle cell anemia can cause acute chest syndrome. Patients with this syndrome often have chest pain, fever, and cough. Carbon monoxide poisoning may trigger coronary artery spasm.


A. Symptoms

Myocardial ischemia is usually described as a dull, aching sensation of “pressure,” “tightness,” “squeezing,” or “gas,” rather than as sharp or spasmodic. Ischemic symptoms usually subside within 5–20 minutes but may last longer. Progressive symptoms or symptoms at rest may represent unstable angina. Prolonged chest pain episodes might represent myocardial infarction, although up to one-third of patients with acute myocardial infarction do not report chest ...
