Recent loss of Saroj Khan from cardiac arrest did raise a lot of queries in regards to this disease. Here’s what this expert has to say
There are times when we all are struggling with various different happenings surrounding us. The recent incident where we lost a Bollywood veteran choreographer Saroj Khan to a cardiac arrest, it has made to the need of taking that extra care of your heart health in these pandemic times. To help you explain the ABC of cardiac arrest, Dr Santosh Kumar Dora, Senior Cardiologist, Asian Heart Institute, Mumbai explains it all to stay safe from this fatal heart concern, if not properly diagnosed on time: What Is Cardiac Arrest? Heart functions as a pump. It receives the deoxygenated blood from veins and pumps to lungs for oxygenation (right heart), then receives pure blood from the lungs to the whole body (left heart). Cardiac arrest is said to happen when this pumping function abruptly stops. It happens when the heart does not beat at all or beats so fast that the pumping becomes completely functionally ineffective.
Symptoms Of Cardiac Arrest: Cardiac arrest leads to sudden cardiac death. Within seconds of cardiac arrest, the person collapses, falls to the ground and becomes unconscious—the heartbeat and breathing stop. Unless cardiopulmonary resuscitation is started immediately and continued till shock therapy (defibrillation) is given, the person dies in a few minutes.
Difference Between Heart Attack And Cardiac Arrest
Three arteries provide blood supply to the heart muscle. If one of these arteries get suddenly blocked by a blood clot, then a heart attack happens. It leads to complete stoppage of blood supply to the areas of the heart where it was supplied earlier. The affected heart muscle does not function any more. The commonest symptom of heart attack is severe pain at the middle of the chest behind the central breastbone.
In some cases, the pain may radiate to arms and jaw. Some patients with a heart attack may just have excessive breathlessness or sweating with mild chest heaviness. Some may present just with vomiting. Following heart attack, the patient should be immediately taken to the hospital, where certain blood thinners and cholesterol-reducing drugs are given. Then the blocked artery is opened up by either clot-busting drug injection, or angioplasty is performed.
Up to 30% of patients suffering from a heart attack may develop cardiac arrest when the heart stops functioning. If you witness such incidence when a patient just collapses in front of you and becomes pulseless, does not breath and is unconscious, then call an ambulance and start cardiac massage immediately. If possible and feasible do mouth to mouth breathing ( twice every 30 compressions). Continue cardiac massage until help arrives. The paramedical persons in an ambulance will have the defibrillator to deliver a shock to revert back from cardiac arrest to a normal rhythm.
Causes Of Cardiac Arrest
A heart attack is one of the most common causes of cardiac arrest. As described before, 30% of patients suffering from a heart attack may develop cardiac arrest. There are several other causes of cardiac arrest too. Heart block, an electrical conduction abnormality may lead to cardiac arrest, if current does not flow to the lower chamber of the heart. Low heart pumping function is one of the strongest predictors of cardiac arrest. Cardiac tamponade, a condition when fluid accumulates around the heart and compresses the heart chamber may lead to cardiac arrest as the heart cannot pump any more. Ventricular arrhythmias caused by cellular ion channel abnormality, hypokalemia and hyperkalemia are the other causes of cardiac arrest.
Protect Yourself From Cardiac Arrest
A heart attack is the commonest cause of cardiac arrest. So we should put maximum effort to prevent a heart attack:
- Heart attack can be prevented by good lifestyle measures and effective treatment of conditions like diabetes, hypertension and dyslipidemia. Smoking should be completely stopped.
- Diet should be of low in fat and sugar. One should exercise daily for 30 to 45 mins, at least five days a week. Weight should be optimal for height.
In patients who already have heart disease, some may have a high risk of cardiac arrests such as patients who have low heart pumping function and patients who have frequent extra beats. The doctor evaluates these patients and determines whether they are of high risk for cardiac arrest. Such patients may benefit from AICD (automatic implantable cardioverter and defibrillator) device implantation. This device protects from sudden cardiac death by delivering appropriate therapy within seconds of cardiac arrest.
Do’s and Don’ts For Patients With A Cardiac Arrest History
- Give the emergency numbers to your family members and colleagues, so that they may call for help in case such a situation arises. If possible train your family members and colleagues at the office on CPR (cardiopulmonary resuscitation) so that it can be performed till help arrives.
- Follow up with your doctor regularly for routine blood parameter and cardiac check-ups.
- If you have undergone AICD implantation because of previous cardiac arrest, your AICD device will be interrogated in periodic intervals by your doctor to know about the functioning and if required any programming.
- Have a healthy diet. Salt intake should be less. If your heart pumping function is low, then your doctor may advise taking less fluid. Follow these instructions strictly.
- Do some physical activity. Walking for 30 mins every day is good exercise. Do not overexert yourself.
- Take medicines regularly as prescribed by your doctor.
- Follow a good diet for overall health. Watch video below:
- Avoid unhealthy diet. Do not take too much of salt and water. If your heart pumping is low, the excess of salt and water intake may lead to pulmonary oedema, a condition where lungs are flooded with fluid which makes breathing difficult. It is a life-threatening condition.
- Do not over-exercise. It may trigger cardiac arrest.
- Do not miss your pills.
- Do not smoke at all.
