Heart Attack vs. Cardiac Arrest: Spotting the Critical Differences

Priya grabbed her chest while cooking dinner Tuesday night. She felt short of breath, like she could not catch her wind. Her husband told her to sit and relax. By 2 AM, she collapsed. Paramedics rushed her to hospital, but it was too late. What Priya did not know, what most people do not know, is her shortness of breath was a warning sign. Research shows half of cardiac arrest victims have symptoms 24 hours before collapse. For women like Priya, that breathlessness triples cardiac arrest risk. Had she known the difference between heart attack and cardiac arrest, her story might have ended differently.

A heart attack blocks blood flow to the heart. Cardiac arrest stops the heart's electrical rhythm. These sound similar but demand different actions. Here is what you need to know to spot the differences and save lives.

The Plumbing vs Electricity Problem

Think of your heart like a house. A heart attack clogs the pipes. Blood can not reach part of the heart muscle, so that tissue starts dying. The heart usually keeps beating during this plumbing crisis.

Cardiac arrest shorts the electrical wiring. The heart's rhythm goes haywire, often ventricular fibrillation where lower chambers quiver uselessly at 500 beats per minute. No blood pumps to brain or lungs. You collapse in seconds.

Here is what most websites miss: a heart attack can trigger cardiac arrest. Scar tissue from damaged heart muscle creates electrical short circuits. But most heart attacks do not immediately cause arrest. When arrest happens, heart attack caused 80% of cases.​

Feature	Heart Attack	Cardiac Arrest
Problem	Blocked artery	Faulty rhythm
Heartbeat	Usually continues	Stops suddenly
Consciousness	Usually awake	Collapse in seconds
Time to act	Hours	Minutes

Warning Signs You Need to Know Now

Here is the surprising truth most websites ignore: Half of cardiac arrest patients had warning signs 24 hours before collapse. These differ dramatically by gender.

Women: Your Biggest Red Flag

Shortness of breath triples cardiac arrest risk for women. Not during exercise, sudden breathlessness at rest. Women also report:​

• Unusual fatigue
• Nausea or flu-like symptoms
• Lightheadedness
• Jaw, neck, or back pain

Priya ignored her cooking breathlessness. Many women dismiss it as anxiety. Do not.

Men: Chest Pain Rules

Men face double cardiac arrest risk with chest pressure. Other signs:​

• Heavy sweating
• Arm or shoulder pain
• Shortness of breath

What doctors rarely tell families: Women survive cardiac arrest at half the rate of men (22% vs 36%). Why? Fewer get bystander CPR. Less likely to have "shockable" rhythms. Hospitals give women fewer life-saving treatments.​

The Deadly 7-Minute Window

Every minute without CPR during cardiac arrest drops survival by 7-10%. Here is the brutal timeline:​

Minutes Without CPR	Survival Chance
1 minute	90%
5 minutes	50%
10 minutes	<10%
15+ minutes	Near zero

What most people do not realize: Hospital data shows 22% survive at 1 minute CPR, but under 1% survive past 39 minutes. If someone has not responded after 40 minutes in hospital, even with perfect CPR, survival becomes statistically impossible.​

Heart attacks give more time. Get to a hospital within 12 hours, and 90% survive with treatment. Cardiac arrest waits for no one.

Why Women's Hearts Fail Differently

The hidden crisis: Women die more from cardiac arrest because the system fails them. Not biology, systemic problems:

• Home arrests: 55% of women's cardiac arrests happen home alone​
• Less CPR: Only 49% of women get bystander CPR vs 55% men​
• Wrong rhythms: Women have "non-shockable" rhythms 75% of time vs men's 55%​
• Less treatment: Fewer women get defibrillators or artery-opening procedures​

At Germanten Hospital, our heart specialists in Hyderabad use protocols ensuring equal treatment. No gender gaps here.

What Ventricular Fibrillation Feels Like (And Why It Kills)

Most websites skip this. Ventricular fibrillation (VF) causes 70% of cardiac arrests. Here is what happens:

1. Coarse VF (first 5 minutes): Heart quivers visibly on monitors
2. Fine VF (5-15 minutes): Weaker quivering, harder to shock
3. Asystole (15+ minutes): Flatline. Heart stopped completely

Survival drops because fine VF resists defibrillator shocks. Shockable rhythms (VF/VT) have 20 times better odds than flatline.​

Your Emergency Action Plan

Heart Attack Response

1. Call emergency services
2. Chew aspirin (325mg) if no allergy
3. Sit comfortably, loosen clothing
4. Stay calm, talk normally

Cardiac Arrest Response - Seconds Count

1. Yell for help - "Call 112! Get AED!"
2. Check response - shake shoulders, shout
3. No breathing, no pulse? START CPR NOW
   • Hands center chest, 2 inches deep
   • 100-120 compressions/minute ("Stayin' Alive" rhythm)
   • Do not stop for breaths
4. AED arrives - follow voice prompts

Cardio pulmonary resuscitation doubles survival when started immediately. Every second counts.​

The Silent Recovery Crisis

What NO other hospital website mentions: Cardiac arrest survivors face massive psychological trauma.

• 40% get anxiety, 30% depression, 25% PTSD​
• Caregivers suffer worse: 50% PTSD vs 21% survivors​
• Hypervigilance: Survivors obsess over every heartbeat
• Avoidance: Fear hospitals, exercise, even crowds

Priya's husband never recovered. He watched CPR, felt helpless. Caregiver PTSD now cripples families.

Recovery phases matter:

• 0-20 minutes: Stabilize after restart
• 20 minutes-12 hours: Cool body, check arteries
• 12-72 hours: Watch brain swelling
• 3+ days: Rehab begins

55% achieve good recovery at 1 year. But psychological support makes the difference.​

Prevention That Actually Works

Heart Attack Prevention

• Quit smoking completely
• Walk briskly 30 minutes daily
• Eat fish, nuts, olive oil (Mediterranean diet)
• Control blood pressure under 120/80
• Daily baby aspirin if doctor approves

Cardiac Arrest Prevention

• ICD implant cuts death risk 50% for high-risk patients​
• Screen family history (Long QT syndrome)
• Fix electrolyte imbalances (low potassium)
• Beta-blockers for known arrhythmias

Women: unexplained shortness of breath demands immediate evaluation at a heart hospital in Hyderabad.

Survival By the Numbers

Factor	Heart Attack	Cardiac Arrest
Immediate survival	90-95% treated	10-15% overall
With CPR/AED <5 min	N/A	50-70%
1-year survival	85-90%	55-60%
Women's disadvantage	Mild	40% lower

Best pulmonology hospitals in Hyderabad watch breathing patterns. Shortness of breath saves lives when caught early.

What Happens After Survival

Good news: 91% alive at 12 months. Many return to work, travel, normal life. But:​

Cognitive issues affect 30-50%:

• Memory problems
• Slow thinking
• Trouble planning

Physical rehab fixes weakness. Psychological care heals trauma. Comprehensive programs work best.

When to Call Your Pulmonologist

Shortness of breath + heart risk factors = emergency. Our pulmonologist Hyderabad team at Germanten Hospital checks:

• Lung function tests
• Stress echocardiograms
• 24-hour heart rhythm monitors
• Sleep apnea screening (triggers arrhythmias)

Early detection saves lives.
