Apical ballooning syndrome precipitated by hyponatremia
International Journal of Cardiology
|February 7, 2009
Summary
Apical Ballooning Syndrome, a type of cardiomyopathy, can be triggered by hyponatremia. Recognizing this stress-induced condition is crucial for prompt diagnosis and management in at-risk populations.
Area of Science:
- Cardiology
- Endocrinology
- Internal Medicine
Background:
- Apical Ballooning Syndrome (ABS), also known as stress-induced cardiomyopathy, is a transient condition.
- It frequently mimics acute myocardial infarction and predominantly affects postmenopausal women.
- Emotional or physical stress are common triggers, with catecholamine surges implicated in its pathophysiology.
Observation:
- Two unique cases of Apical Ballooning Syndrome were observed.
- These cases were triggered by hyponatremia, an often overlooked electrolyte imbalance.
- Hyponatremia represents a novel and expanding category of potential triggers for ABS.
Findings:
- Hyponatremia can act as a significant trigger for Apical Ballooning Syndrome.
- This finding broadens the spectrum of known etiologies for stress-induced cardiomyopathy.
- Physicians must consider electrolyte disturbances like hyponatremia in the differential diagnosis of ABS.
Implications:
- Increased physician awareness of hyponatremia as a trigger for ABS is essential.
- Early recognition and correction of hyponatremia may aid in managing ABS.
- Further research is warranted to elucidate the mechanisms linking hyponatremia to ABS pathophysiology.

01:29Disorder of Water Balance
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...

01:21Hyperosmolar Hyperglycemic State
Hyperosmolar Hyperglycemic State, or HHS, is a serious and life-threatening complication of type 2 diabetes mellitus. It is characterized by three main features: severe hyperglycemia, profound dehydration, and elevated serum osmolality, all occurring without significant ketoacidosis.HHS typically develops in older adults or individuals with limited access to fluids. This may result from illness, cognitive impairment, or medications such as diuretics or corticosteroids. These factors reduce...
01:19Ascites
DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
01:21Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:18Pulmonary Edema II: Pathophysiology
Pulmonary edema is the accumulation of fluid in the interstitial and alveolar spaces of the lungs, impairing gas exchange and oxygen delivery. It may be cardiogenic or noncardiogenic, but both reduce oxygenation and lung compliance.Cardiogenic Pulmonary EdemaCardiogenic edema results from increased hydrostatic pressure in pulmonary capillaries, usually due to left ventricular dysfunction from myocardial infarction, heart failure, or valvular disease. Ineffective cardiac pumping causes blood to...
