Heart Enlargement Case Study: Effective Treatment and Recovery from Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy is one of the most common forms of heart muscle disease, characterized by abnormal thickening of the heart muscle. This article presents a real-life case involving a 56-year-old female patient who experienced episodic chest tightness, chest pain, and sweating after physical activity. After a comprehensive medical evaluation, she was diagnosed with hypertrophic cardiomyopathy and successfully treated with a combination of medications. Her symptoms were fully alleviated within a week of hospitalization, and follow-up one month later confirmed sustained improvement.

Patient Overview

• Age & Gender: 56-year-old female
• Medical Condition: Heart enlargement due to hypertrophic cardiomyopathy
• Treatment Facility: First Affiliated Hospital of Xi'an Jiaotong University
• Visit Date: March 2022
• Treatment Approach: Oral medications including Metoprolol Tartrate, Amiodarone Hydrochloride, Spironolactone, and Warfarin Sodium
• Hospitalization Duration: 7 days
• Follow-up: One-month post-discharge evaluation
• Outcome: Stable condition with complete resolution of symptoms

Initial Presentation and Diagnosis

The patient reported experiencing intermittent chest discomfort and pain that occurred during physical exertion. These symptoms appeared in three separate episodes over a six-hour period, each lasting only a few seconds and resolving with rest. No additional symptoms were noted, and she had not sought any prior treatment.

Upon physical examination, her heart rate and pulse were both recorded at 65 beats per minute with a regular rhythm. No abnormal heart sounds, murmurs, or signs of cardiac enlargement were detected. An electrocardiogram (ECG) revealed left ventricular high voltage and ST-T segment abnormalities, suggesting underlying cardiac strain. Further investigation with an echocardiogram confirmed regional myocardial dysfunction and left atrial enlargement, leading to a diagnosis of hypertrophic cardiomyopathy.

Treatment Strategy and Progress

Following admission, the patient underwent a series of cardiac tests. Blood markers including troponin I (0.01 ng/mL), creatine kinase-MB (4.06 ng/mL), and myoglobin (<30 ng/mL) were all within normal ranges, ruling out acute myocardial injury.

A tailored medical regimen was initiated after consultation with the patient:

• Metoprolol Tartrate – A beta-blocker to reduce heart rate and myocardial contractility
• Amiodarone Hydrochloride – To lower the risk of atrial fibrillation
• Spironolactone – A diuretic to reduce fluid retention and cardiac workload
• Warfarin Sodium – An anticoagulant to prevent thromboembolic events

This combination therapy was well tolerated and led to significant improvement in symptoms within a short time.

Outcome and Follow-up

Prior to treatment, the patient frequently experienced chest tightness, pain, and sweating. After one week of targeted therapy, these symptoms were completely resolved. Upon physical examination at discharge, her heart rhythm remained regular, and no structural abnormalities were observed. She was cleared for discharge with instructions to continue medication and schedule a follow-up visit after one month.

At the follow-up appointment, the patient remained asymptomatic and reported high satisfaction with the treatment outcome. The medical team concluded that the therapeutic approach was effective and sustainable.

Post-Treatment Recommendations

To maintain long-term cardiac health, the following lifestyle and medical adherence guidelines were emphasized:

1. Medication Compliance: It is critical to continue prescribed medications without interruption or dosage changes unless directed by a physician.
2. Nutrition: A balanced diet rich in lean proteins such as eggs and poultry can support overall recovery and cardiovascular function.
3. Exercise: Low-impact physical activities like yoga or jogging are encouraged to improve cardiovascular endurance, provided they are performed within the individual's tolerance level.

Clinical Insight and Patient Education

This case illustrates that hypertrophic cardiomyopathy may not always present with obvious physical signs such as an enlarged heart. However, echocardiography can detect subtle structural changes that are crucial for early diagnosis.

Timely recognition of symptoms such as chest discomfort, fatigue, palpitations, or shortness of breath is essential. Delaying medical evaluation may lead to serious complications. Early diagnosis and proper management can significantly improve prognosis and quality of life.
