Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Rapid heart rate
Heart rate exceeds 100 beats per minute as the heart attempts to compensate for reduced cardiac output.
Seek immediate medical attention if heart rate exceeds 120 beats per minute with chest pain, dizziness, or shortness of breath.
Low blood pressure
Blood pressure drops below normal ranges, often below 90/60 mmHg, due to inadequate cardiac pumping.
Seek emergency care immediately if blood pressure falls below 80/50 mmHg or if you experience fainting, confusion, or chest pain.
Shortness of breath
(respiratory)Difficulty breathing or feeling winded, often occurring at rest or with minimal exertion due to fluid backup in the lungs.
Frequency: 70-80% of patients
Fatigue and weakness
(constitutional)Persistent tiredness and lack of energy due to reduced oxygen delivery to tissues throughout the body.
Frequency: 65-75% of patients
Cool, clammy skin
(dermatologic)Skin feels cold and moist as the body redirects blood flow to vital organs, often appearing pale or mottled.
Frequency: 50-60% of patients
Decreased urine output
(renal)Reduced urine production, often less than 0.5 mL/kg/hour, indicating poor kidney perfusion.
Frequency: 45-55% of patients
Chest discomfort
(cardiovascular)Pressure, tightness, or pain in the chest area caused by reduced blood flow to the heart muscle.
Frequency: 40-50% of patients
Lightheadedness
(neurologic)Feeling faint or dizzy, often when standing up quickly, caused by inadequate blood flow to the brain.
Frequency: 35-45% of patients
Irregular heartbeat
(cardiovascular)Heart rhythm abnormalities such as palpitations, fluttering, or skipped beats due to cardiac stress.
Frequency: 20-30% of patients
Confusion
(neurologic)Mental confusion, difficulty concentrating, or altered consciousness due to reduced blood flow and oxygen to the brain.
Frequency: 15-25% 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
Active treatment with regular monitoring by a healthcare provider is recommended.
Inotropic support therapy
Use of positive inotropic agents to enhance cardiac contractility and improve cardiac index. These medications work by increasing calcium influx into myocardial cells, thereby improving the heart's pumping efficiency.
Fluid management and optimization
Careful assessment and titration of intravascular volume status using bedside monitoring tools. Goal-directed fluid therapy helps optimize preload while avoiding fluid overload that can worsen cardiac function.
Additional treatment options
Sodium and fluid restriction
Implementation of dietary sodium restriction (typically 2-3g daily) combined with fluid management to reduce cardiac workload. This approach minimizes fluid retention and decreases preload on the heart.
dietaryContinuous hemodynamic monitoring
Use of arterial lines, central venous pressure monitoring, or non-invasive cardiac output monitoring to guide therapeutic decisions. Continuous assessment allows for real-time treatment optimization.
monitoringActivity modification and pacing
Gradual reintroduction of physical activity with appropriate rest periods to prevent cardiac decompensation. Energy conservation techniques help patients perform daily activities without excessive cardiac stress.
lifestyleWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
