Cardiac arrest is a sudden and life-threatening medical emergency in which the heart abruptly stops pumping blood effectively. While often associated with older adults, cardiac arrest can occur at any age, including in children and young adults, with causes and outcomes varying significantly across life stages.
In this blog, we explain how cardiac arrest affects people of different ages, highlighting age-specific risks, early warning signs, and preventive strategies.
Cardiac Arrest in Infants and Children
Cardiac arrest in infants and children is uncommon but particularly serious due to rapid physiological deterioration. Unlike adults, paediatric cases are less often linked to coronary artery disease. Instead, they usually arise from underlying medical or respiratory conditions that interfere with oxygen delivery or heart rhythm.
In younger age groups, the reason for cardiac arrest is frequently non-cardiac in origin, with breathing problems playing a significant role.
Common cardiopulmonary arrest causes in infants and children include the following.
- Congenital heart defects that affect heart structure or electrical pathways
- Severe respiratory infections leading to oxygen deprivation
- Near-drowning or choking incidents
- Severe trauma or accidental poisoning
- Genetic rhythm disorders affecting heart conduction
Symptoms in children may be subtle and easily missed. These can include sudden collapse, unresponsiveness, abnormal breathing, or bluish discolouration of lips and skin. Because children cannot always communicate discomfort clearly, delays in treatment are more likely when caretakers are unaware of the pain.
Access to specialised care at an advanced heart hospital in Delhi NCR ensures that children with known heart conditions receive continuous monitoring, early diagnosis, and preventive treatment under expert supervision.

Cardiac Arrest in Adolescents and Young Adults
Cardiac arrest in adolescents and young adults is often unexpected, as this age group is generally perceived as healthy. However, certain inherited, structural, and lifestyle-related factors can increase vulnerability.
In younger adults, the reason for cardiac arrest is commonly linked to undiagnosed heart rhythm disorders or structural abnormalities. High-intensity physical activity can sometimes act as a trigger, especially when underlying heart conditions are present.
Key cardiopulmonary arrest causes among adolescents and young adults include the following:
- Inherited electrical disorders such as long QT syndrome
- Hypertrophic cardiomyopathy affects heart muscle thickness.
- Inflammation of the heart muscle following viral infections
- Substance misuse, including recreational drugs and excessive alcohol
- Intense physical exertion without prior cardiac screening
Symptoms before an event may include unexplained fainting, chest discomfort during exercise, palpitations, or shortness of breath. These warning signs are frequently overlooked or attributed to fatigue or stress. Consultation with a qualified heart specialist in Delhi NCR allows early investigation through ECGs, imaging, and family history assessment.
Cardiac Arrest in Middle-Aged Adults
In this age group, the reason for cardiac arrest is most commonly related to coronary artery disease, where narrowed blood vessels reduce oxygen supply to the heart muscle. Over time, this can trigger dangerous heart rhythms.
Common cardiopulmonary arrest causes in middle-aged adults include the following:
- Long-standing high blood pressure and diabetes
- High cholesterol leads to plaque formation in the arteries.
- Smoking and sedentary lifestyle habits
- Obesity and poor dietary patterns
- Previous heart attack or untreated heart disease
Symptoms may include chest pain, breathlessness, extreme fatigue, dizziness, or sudden collapse. Regular cardiac evaluations at a recognised Cardiology hospital in Delhi NCR can help detect silent heart disease before it leads to cardiac arrest.

Cardiac Arrest in Older Adults
Older adults face the highest overall risk of cardiac arrest, mainly due to age-related changes in the heart and blood vessels. As the body ages, the heart muscle may weaken, arteries can stiffen, and electrical conduction pathways may become unstable.
In this age group, the reason for cardiac arrest is most often linked to advanced coronary artery disease, heart failure, or long-standing rhythm disturbances.
The most frequent cardiopulmonary arrest causes in older adults include the following:
- Severe narrowing or blockage of the coronary arteries
- Heart failure with reduced pumping capacity
- Chronic arrhythmias such as ventricular tachycardia
- Electrolyte imbalances due to kidney disease or medications
- Complications from previous heart attacks
Warning signs may include worsening breathlessness, swelling of the legs, unexplained fatigue, confusion, or sudden collapse. Regular monitoring by a skilled heart specialist in Noida is essential for early detection of deterioration.
Importance of Age-Specific Cardiac Care and Prevention
Risk factors, warning signs, and treatment priorities vary widely between children, young adults, middle-aged individuals, and older adults.
Age-focused evaluation helps identify the underlying reason for cardiac arrest more accurately and allows clinicians to address the most relevant cardiopulmonary arrest causes for each life stage.
Key elements of age-specific cardiac care include the following:
- Early screening for congenital or inherited heart conditions in children
- Sports- and lifestyle-related cardiac assessment in young adults
- Risk factor control and disease management in middle age
- Comprehensive monitoring and rehabilitation in older adults
Consulting a qualified cardiologist in Faridabad ensures that patients receive personalised guidance, evidence-based treatment, and long-term monitoring.
