People may be unaware of what is truly happening in their bodies throughout these three occurrences.
- During a heart attack, the blood supply to the heart muscles is obstructed, causing the cardiac muscle to stop pumping blood (circulation problem).
- During a cardiac arrest, the conduction system of the heart fails, and the heart develops asystole (no heartbeat is generated).
- A stroke is the obstructed blood supply to the brain vessels causing symptoms such as the inability to move a body part, unconsciousness, and inability to speak clearly.
What is a heart attack?
Heart attack is, at its core, an issue with blood circulation, and it occurs when blood flow in a person's heart is significantly restricted or severely blocked.
- Heart attacks range in severity from quite mild to extremely catastrophic or serious.
- It occurs when an artery becomes blocked, preventing oxygen-rich blood from reaching a region of the heart that needs it.
- The section of the heart that is regularly supplied by a blocked artery may begin to die if the blocked artery is not opened immediately.
The longer a person goes without treatment, the more serious the consequences become. Symptoms might sometimes appear gradually and continue for many hours, days, or even weeks before a heart attack occurs.
Symptoms of a heart attack in men
- The majority of heart attacks generally involve painful pressure, squeezing, or discomfort in the middle of the chest that may linger for many minutes or even hours. This soreness might come and go at any time throughout the day.
- Upper-body soreness or discomfort in one or both arms and pain in the back, neck, jaw, or stomach are all common symptoms of this condition.
- Long-term shortness of breath along with or without chest pain is a common symptom of a heart attack.
Symptoms of a heart attack in women
- Discomfort in the neck, jaw, shoulders, or upper back or upper abdomen
- Fatigue or fainting
- Flu-like symptoms
- Light-headedness or dizziness
- Short breath
- Pain in the left arm or both arms
- Heartburn (because of indigestion)
Apart from these, women can experience the same symptoms as those in men.
What is a cardiac arrest?
Cardiac arrest is an electrical disorder that occurs when a person's heart stops beating abruptly and unexpectedly, preventing blood and oxygen from reaching essential organs. It is caused by a malfunctioning electrical system.
Sudden cardiac arrest (SCA), in contrast to a heart attack, is always life-threatening. Cardiac arrest occurs abruptly and without warning, and it is generally fatal. It is characterized by a sudden loss of cardiac function. It might be brought on by an irregular heartbeat (arrhythmia).
- Ventricular fibrillation is a frequent arrhythmia that occurs in the context of cardiac arrest and is a condition in which the heart's lower chambers (ventricles) suddenly begin to beat chaotically and fail to pump blood to the brain, lungs, and other organs as they should. Within seconds, the individual loses consciousness and stops breathing.
- SCA may be caused by various factors, including ventricular fibrillation, a violent shock to the chest, electrocution, drowning, drug addiction, cardiac attacks, cardiomyopathy, or hypothermia. Ventricular fibrillation is the most common cause of SCA.
If defibrillation (which shocks the heart and restores a normal heart rhythm) is done within minutes, it may help reverse cardiac arrest. Cardiopulmonary resuscitation is the most effective way to reverse cardiac arrest. If proper steps are not taken immediately, death can occur.
Symptoms of a cardiac arrest
The beginning of a cardiac arrest might occur with little or no prior notice. Signs and symptoms are rapid and life-threatening.

What is a stroke?
An attack on the brain, also known as a stroke, occurs when blood flow to the brain is interrupted by a clogged or burst of a blood artery. A stroke may occur at any moment and can occur to anybody at any age.
- Because the brain cells are starved of oxygen when the blood supply to the brain is interrupted, the brain cells begin to die.
- When the brain cells die after a stroke, few functions such as memory and muscular activity that are regulated by that part of the brain are totally lost.
Appropriate treatment in a timely manner is essential to avoid brain injury and subsequent problems. Stroke is a serious and fatal condition.
There are many forms of stroke, but the three types of stroke include:
- Hemorrhagic stroke: A hemorrhagic stroke occurs when a damaged blood artery ruptures and bleeds. Uncontrolled hypertension is the most prevalent cause of a hemorrhagic stroke.
- Ischemic stroke: An ischemic stroke develops when the blood flow to the brain is impeded or clots in a vessel. It is responsible for about 87 percent of all strokes. Atherosclerosis, or fatty deposits lining the artery walls, is the primary cause of an ischemic stroke.
- Transient ischemic attack (TIA): TIA occurs when the blood supply to the brain is temporarily blocked. It is caused by a significant transient clot. It does not cause much harm and is often overlooked, and the harms are not long-lasting. TIA may be a precursor to a full-blown stroke.
Symptoms of a stroke
To discuss symptoms of a stroke, the acronym FAST is used.
- F (face): If someone's face starts to droop or they complain of numbness, one can encourage them to smile. If a person's smile is asymmetrical or lopsided, they may be suffering from a stroke.
- A (arm): Ask the person to lift both arms if their arm is weak or numb. If one arm is inclined downward, then it may be a sign of a stroke.
- S (speech): If the speech is slurred or sounds strange, then also it is a sign.
- T (time): If someone has any of the abovementioned symptoms, then the person should be taken to the hospital immediately.

What Are the Four Signs of an Impending Heart Attack?A heart attack occurs when the blood vessel that supplies blood to your heart (coronary artery) gets blocked – partially or completely. The lack of blood supply means the heart does not get enough oxygen or nutrients.
Heart Attack PreventionHeart disease and heart attacks can be prevented by leading a healthy lifestyle with diet, exercise, and stress management. Symptoms of heart attack in men and women include chest discomfort and pain in the shoulder, neck, jaw, stomach, or back.
Heart Attack Treatment
A heart attack involves damage or death of part of the heart muscle due to a blood clot. The aim of heart attack treatment is to prevent or stop this damage to the heart muscle. Heart attack treatments included medications, procedures, and surgeries to protect the heart muscle against injury.

StrokeA stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
Cardiac Arrest QuizTake the Sudden Cardiac Arrest Quiz. Learning about this potentially deadly condition may save a life.
Sudden Cardiac ArrestSudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive) abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol,Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.
Types of StrokesA stroke, also called cerebrovascular accident (CVA), occurs when the blood supply is cut off or reduced to a part of the brain. There are five main types of strokes, and the causes and clinical presentation of each of them vary
Warning Signs of a StrokeSigns of a stroke may sometimes go unnoticed initially and gradually progress. Sometimes, the signs of a stroke may appear suddenly.
