From the Guidelines
Management of acute chest conditions, including acute coronary syndrome (ACS) and community-acquired pneumonia (CAP), requires prompt assessment and targeted interventions, with the most recent guidelines from 2015 (1) emphasizing the importance of immediate administration of aspirin and antiplatelet therapy for ACS, and empiric antibiotic therapy for CAP. For acute coronary syndrome (ACS), the guidelines recommend:
- Immediate administration of aspirin (325mg chewed) 1
- Antiplatelet therapy with P2Y12 inhibitors like clopidogrel (300-600mg loading dose, then 75mg daily) or ticagrelor (180mg loading dose, then 90mg twice daily) 1
- Anticoagulation with heparin or low-molecular-weight heparin, along with high-intensity statins, beta-blockers, and ACE inhibitors as appropriate 1
- Reperfusion therapy through primary PCI is preferred for STEMI if available within 90 minutes; otherwise, fibrinolytic therapy should be considered 1 For community-acquired pneumonia (CAP), the guidelines recommend:
- Empiric antibiotic therapy should begin within 4-6 hours of presentation 1
- Outpatient treatment typically includes amoxicillin (1g three times daily for 5 days) or doxycycline (100mg twice daily for 5 days) 1
- For hospitalized non-ICU patients, a respiratory fluoroquinolone like levofloxacin (750mg daily) or combination therapy with a beta-lactam plus a macrolide is recommended 1
- Severe CAP requiring ICU admission warrants broader coverage with a beta-lactam plus either azithromycin or a respiratory fluoroquinolone 1 Some key considerations in managing acute chest conditions include:
- Risk stratification to determine the severity of disease and guide treatment decisions 1
- Early identification of the causative pathogen through appropriate cultures and sensitivity testing to allow for targeted antibiotic therapy 1
- Supplemental oxygen and fluid resuscitation as needed to maintain oxygen saturation above 90% and support cardiovascular function 1

Guidelines for Managing Acute Chest Conditions
The management of acute chest conditions, including acute coronary syndrome (ACS) and community-acquired pneumonia (CAP), involves several key guidelines.
- Acute Coronary Syndrome (ACS) Management:
- Aspirin is recommended for all patients with suspected ACS unless contraindicated 2.
- Dual antiplatelet therapy (e.g., clopidogrel, ticagrelor, or prasugrel) is also recommended for most patients 2.
- Parenteral anticoagulation with unfractionated heparin, low-molecular-weight heparin, bivalirudin, or fondaparinux is recommended 2.
- Proton pump inhibitors are recommended to prevent bleeding due to antiplatelet and anticoagulation use in patients at higher risk of gastrointestinal bleeding 2.
- Other medical therapies should include statins, angiotensin-converting enzyme inhibitors, beta blockers, nitroglycerin, and morphine (to relieve chest pain), and oxygen 2.
- ST-Segment Elevation Myocardial Infarction (STEMI) Management:
- Non-ST-Segment Elevation ACS (NSTE-ACS) Management:
- PCI is recommended; fibrinolytic therapy typically is not recommended 2.
- High-sensitivity troponin measurements are the preferred test to evaluate for NSTEMI 3.
- In high-risk patients with NSTE-ACS and no contraindications, prompt invasive coronary angiography and percutaneous or surgical revascularization within 24 to 48 hours are associated with a reduction in death 3.
- Prehospital Administration of Aspirin and Nitroglycerin:
- Prehospital administration of aspirin and nitroglycerin by non-physician healthcare professionals is beneficial for patients with suspected ACS, although the certainty of evidence is very low 4.
- Early administration of aspirin (within two hours) following the onset of chest pain as part of first-aid management is associated with increased survival compared with late administration 5.
