Different Origin: A heart attack is caused by a blockage in the blood vessels supplying the heart, while cardiac arrest occurs when the heart suddenly stops beating.
Mechanism of Injury: A heart attack damages the heart muscle due to insufficient blood flow, whereas cardiac arrest disrupts the heart's electrical system, leading to a sudden stoppage.
Warning Signs: Heart attacks often exhibit symptoms like chest pain, shortness of breath, and nausea, while cardiac arrest strikes suddenly without warning.
Age Group: Heart attacks are more common in older individuals, whereas cardiac arrest can occur in people of all ages, even seemingly healthy individuals.
Risk Factors: Heart attacks are often linked to lifestyle factors like smoking, obesity, and high cholesterol, while cardiac arrest can be caused by underlying heart conditions or genetic factors.
Time Sensitivity: Heart attacks require urgent medical attention to prevent further damage, whereas cardiac arrest demands immediate CPR and defibrillation to restart the heart.
Treatment Differences: Heart attacks are managed through medications, and procedures like angioplasty, or surgery, whereas cardiac arrest is primarily addressed with life-saving interventions like CPR and defibrillation.
