Summary
Severe hypocalcaemia, a rare condition, can cause reversible heart failure. Prompt calcium supplementation rapidly restored heart function in a patient with hypoparathyroidism.
Area of Science:
- Cardiology
- Endocrinology
- Internal Medicine
Background:
- Hypocalcaemia is an uncommon cause of heart failure.
- Post-thyroidectomy hypoparathyroidism can lead to severe hypocalcaemia.
Observation:
- A 76-year-old woman presented with severe systolic heart failure.
- Echocardiography revealed a dilated left ventricle and reduced ejection fraction.
- Laboratory tests confirmed severe hypocalcaemia without other abnormalities.
Findings:
- Calcium supplementation led to rapid improvement in heart failure symptoms.
- Biventricular systolic and diastolic functions normalized within two months.
- Restored serum calcium levels correlated with cardiac function recovery.
Implications:
- Highlights hypocalcaemia as a treatable cause of heart failure.
- Emphasizes the importance of monitoring calcium levels post-thyroidectomy.
- Suggests calcium supplementation as a key intervention for cardiac recovery in hypocalcaemic patients.

01:30Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:29Cardiomyopathy V: Interprofessional Care
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
01:25Cardiomyopathy I: Introduction and Classification
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
01:30Coronary Artery Disease III: Clinical Manifestations
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
01:29Cardiomyopathy VI: Nursing Management
Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops),...
