Sexual Activity After Myocardial Infarction
For uncomplicated MI, sexual activity can be safely resumed at 1-2 weeks post-event when the patient can perform mild to moderate physical activity without cardiac symptoms. 1
Risk Stratification Framework
The timing of sexual activity resumption depends critically on MI complexity and functional capacity:
Uncomplicated MI (Low Risk)
- Resume sexual activity at 1-2 weeks if asymptomatic during mild-moderate physical activity 1
- Patients who are stable without complications (Class I recommendation) can resume sexual activity with their usual partner within 1 week to 10 days 1
- The key criterion is absence of cardiac symptoms (chest pain, dyspnea, arrhythmias) during daily activities 1
Complicated MI (Higher Risk)
- Resume sexual activity more gradually over several weeks to months, depending on exercise tolerance 1
- Complicated MI includes those requiring CPR, accompanied by hypotension, serious arrhythmias, high-degree heart block, or heart failure 1
- These patients require stabilization and optimization of medical management before resuming sexual activity 1
Functional Capacity Assessment
Sexual activity is reasonable when patients can achieve 3-5 METs without symptoms 1:
- Sexual activity typically requires 3-5 METs of energy expenditure (equivalent to walking 3-4 mph or climbing 2 flights of stairs briskly) 1
- If a patient can exercise at 5 METs without angina, excessive dyspnea, ischemic ST-segment changes, cyanosis, hypotension, or arrhythmia, sexual activity is safe 1
- Cardiovascular symptoms during sex rarely occur in patients who don't experience similar symptoms during exercise testing at 6 METs 1
When Exercise Testing is Needed
- Stress testing is recommended for patients with intermediate risk or unclear symptoms during initial assessment 1
- Testing determines whether angina occurs with exertion and assesses ischemia severity 1
- Patients with incomplete coronary revascularization may need stress testing before resuming sexual activity 1
Graduated Approach to Intimacy
Start with lower-energy activities as a bridge to intercourse 1:
- Begin with hugging, kissing, and fondling without genital stimulation (Class IIa recommendation) 1
- This approach is particularly useful for patients with compromised cardiac function who may not tolerate full intercourse 1
- Gradual progression allows assessment of tolerance and reduces anxiety 1
Critical Safety Instructions
Warning Signs During Sexual Activity
Patients must report these symptoms immediately 1:
- Chest pain lasting >15 minutes (or >5 minutes after nitrate use) 1
- Shortness of breath 1
- Rapid or irregular heart rate 1
- Dizziness 1
- Insomnia after sexual activity 1
- Fatigue the day after sexual activity 1
Nitrate Management
- If prescribed, nitroglycerin can be taken prophylactically before sex or during coital angina 1
- Seek emergency services if chest pain doesn't resolve in 15 minutes spontaneously or 5 minutes after nitrate use 1
- Critical caveat: Patients using PDE5 inhibitors (sildenafil, tadalafil, vardenafil) must NEVER use nitrates for coital angina—call emergency services immediately 1
Role of Cardiac Rehabilitation
Regular exercise reduces the risk of sexual activity-triggered MI 1:
- Exercise training during cardiac rehabilitation increases maximum exercise capacity and decreases peak coital heart rate 1
- Regular physical exercise is associated with reduced risk of sexual activity-triggered cardiovascular events 1
- This is a reasonable strategy for patients with stable CVD planning to engage in sexual activity 1
Patient Counseling Essentials
Timing of Discussion
- Most patients prefer general information about sexuality effects while hospitalized 1
- More specific information (ideal settings, positions) can be provided after discharge 1
- Proactive physician counseling is essential—don't wait for patients to ask 2
Addressing Fear
- Post-MI patients commonly fear having another MI during sexual activity 1
- Reassure patients that the relative risk of cardiac events with sexual activity is low 1
- The actual risk of sexual activity-triggered cardiovascular events is very low in properly risk-stratified patients 1
- Most partnered women resume sexual activity within 4 weeks despite fear, often without directed counseling 2
Common Pitfalls to Avoid
- Don't assume patients will ask about sexual activity—few receive counseling unless they initiate the discussion themselves 2
- Don't delay counseling—provide explicit advice about when to return to sexual activity before discharge 1
- Don't forget the partner—both patient and partner often have anxiety and fears that need addressing 1
- Don't overlook that sexual dysfunction often predates the MI—50-75% of patients have pre-existing issues 3
