Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Chest discomfort
Pressure, tightness, squeezing, or pain in the chest that may radiate to the arm, jaw, neck, or back.
Seek immediate emergency care if chest pain is sudden, severe, or accompanied by sweating, nausea, or shortness of breath.
Fainting
Sudden loss of consciousness, often preceded by lightheadedness or weakness, that may result from inadequate blood flow to the brain.
Seek immediate emergency care for any fainting episode, especially if accompanied by chest pain or irregular heartbeat.
Palpitations
(cardiovascular)Awareness of rapid, irregular, or forceful heartbeats that may feel like the heart is pounding, racing, or fluttering.
Frequency: 60-70% of patients
Shortness of breath
(respiratory)Difficulty breathing or feeling breathless, especially during physical activity or when lying flat.
Frequency: 50-60% of patients
Fatigue
(constitutional)Persistent tiredness, weakness, or lack of energy that interferes with daily activities.
Frequency: 40-50% of patients
Dizziness
(neurologic)Feeling lightheaded, unsteady, or like the room is spinning, which may lead to fainting.
Frequency: 20-30% of patients
Leg swelling
(cardiovascular)Swelling or puffiness in the lower legs, ankles, or feet due to fluid retention.
Frequency: 15-25% of patients
Persistent cough
(respiratory)Chronic cough that may be dry or produce frothy or bloody sputum, often worsening when lying down.
Frequency: 15-20% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Cardiac auscultation follow-up
Regular heart sound evaluation and echocardiogram monitoring to track any changes in abnormal heart sounds over time.
Blood pressure management
Antihypertensive therapy when elevated blood pressure contributes to abnormal heart sounds, particularly murmurs from increased flow.
Additional treatment options
Activity modification
Avoidance of strenuous exercise and extreme exertion while cardiac evaluation is ongoing to reduce cardiovascular stress.
lifestyleSodium restriction
Reduced dietary sodium intake to minimize fluid retention and decreased cardiovascular load that may affect heart sound characteristics.
dietaryValve repair evaluation
Surgical assessment for structural heart abnormalities when heart sounds indicate significant valve dysfunction requiring intervention.
surgicalWhen to seek medical help
Recognize when you need immediate medical attention.
