Understanding Heart Disease
Heart disease or cardiovascular disease is a combination of diseases that are related to the heart and the blood vessels.
It has caused the most deaths in India and people should know its types, symptoms and risks to avoid its occurrence and to propose suitable interventions.
The common types of heart diseases are:
Coronary Artery Disease (CAD): The condition occurs when blood supplying arteries to the heart narrow or are blocked and this restricts the oxygen-carrying capacity. CAD is the leading heart attack cause in India.
Arrhythmia: Abnormal heartbeat can interfere with normal functioning of the heart and even lead to sudden cardiac arrest.
Heart Failure: A condition where the pumping capacity of the heart is defective resulting in tiredness, shortness of breath and leg or abdominal body swelling.
Congenital Heart Disease: Birth abnormalities of the intricate organs of the heart that relate to blood circulation and heart activity.
Major Causes of Heart Disease in India
In India, the combination of lifestyle, medical and environmental factors affect heart disease.
Learning these reasons is quite essential to prevent and to act in time before it is too late as the sedentary lifestyles and stress levels are increasing in urban settings.
Lifestyle Factors
Poor Diet: Processed meals, trans fats, too much sugar, and refined carbohydrates are some of the foods that have a high risk of causing heart disease. The fast food is slowly taking the traditional Indian diets, which are associated with high cholesterol, obesity, and arterial blockages.
Physical Inactivity: Sitting jobs, excessive working time, and absence of exercise make the body less fit in terms of cardiovascular fitness, making them more prone to heart complications.
Stress and Mental Health: Continuous stress due to work pressure, financial struggles and problems at the personal level results in a high level of cortisol, which is a factor of high blood pressure and cardiac event.
Tobacco and Alcohol Use: Smoking is one of the most common preventable reasons of the heart disease in India and excessive drinking of alcohol may weaken the heart muscle and lead to arrhythmia.
Medical and Biological Factors
Hypertension (High Blood Pressure): High blood pressure is known as a silent killer as it puts a strain on the heart and damages blood vessels with time making people highly exposed to heart attacks and strokes.
Diabetes: India has a very high diabetes rate in the world. Unmanaged blood sugar levels cause harm to arteries, which hasten atherosclerosis and other heart diseases.
Obesity: This is an excess amount of body weight, especially the fat in the abdominal area, that causes pressure on the heart and elevates blood pressure and chances of coronary artery diseases and heart failure.
High Cholesterol: High LDL (bad cholesterol) levels help in the creation of plaque in the arteries, which limit blood circulation to the heart.
Genetic and Environmental Factors
Family History: A family history of heart disease increases the risk of the disease, and therefore early monitoring and prevention are of great importance.
Environmental Pollution: Air pollution, as seen in most of the Indian cities, has been associated with high levels of cardiovascular disease because of oxidative stress and inflammation.
Heart Disease Symptoms
Early diagnosis of heart disease will save lives.
Symptoms are underestimated or disregarded by many people, and this can slow down treatment and lead to the possibility of severe complications as in the case of sudden cardiac arrest.
Preparedness and education are important in India where there is still an increasing level of awareness regarding these symptoms.
Chest Pain or Discomfort
Chest pain, or chest discomfort, which is usually described as a feeling of pressure, tightness feeling, is one of the most prevalent symptoms of heart disease.
This may be when one is engaged in a physical activity or when an individual is under stress or when one is at rest.
When it comes to coronary artery disease, chest pain can extend to shoulders, arms, neck or jaw.
Shortness of Breath
The efficiency of the heart in pumping blood may be decreased by heart disease which results in shortness of breath particularly during activities such as climbing up the stairs or exercising.
In the worst, even at rest, breathlessness can be experienced.
Fatigue and Weakness
Continuous fatigue or unexplainable fatigue especially when the body takes part in minor physical activities may also show that the heart is not pumping blood properly.
In India, a lot of them tend to view fatigue because of stress or overwork which slows down diagnosis.
Palpitations or Irregular Heartbeats
Arrhythmias are abnormal heart beats, and they can be rapid, fluttering, or irregular. These may even cause sudden cardiac arrest unless they are handled in time.
Abdominal, Ankle, or Leg Swelling
Heart failure may be evidenced by edema of the lower extremities or abdomen or retention of fluid.
The heart cannot pump blood effectively leading to the build-up of fluids in tissues.
Dizziness or Fainting
Periods of dizziness, lightheadedness or fainting can be caused by decreased blood supply to the brain.
These are red flags of the probable severe cardiac diseases, such as arrhythmias.
Silent Heart Disease
It is worth mentioning that the heart disease is sometimes too silent, particularly in women and in the elderly.
There might not be apparent symptoms in the people until a significant event such as a heart attack or sudden death.
Cardiac Arrest vs Myocardial Infarction
Sudden cardiac arrest (SCA) is often mistakenly related to a heart attack, but they are not similar and the difference between the two conditions is important in terms of timely treatment.
Myocardial Infarction (Heart Attack)
The heart attack is the heart failure of supply of blood to a section of the heart muscle and is typically caused by a clot in the coronary arteries.
This leads to damage to heart tissue.
Common symptoms include:
Pain or discomfort in the chest, which tends to extend to the arm, neck, or jaw.
Shortness of breath
Nausea or vomiting
Sweating and fatigue
Although a heart attack may be fatal, the heart may keep on beating, hence emergency treatment may be administered in time in case the symptoms are identified in time.
Sudden Cardiac Arrest (SCA)
Sudden cardiac arrest is a loss of heart rhythm suddenly and unexpectedly, which is commonly caused by an electric shock that occurs in the heart creating an arrhythmia. During SCA:
Pumping of blood is no longer carried out by the heart.
The individual falls at once, faints.
Without intervention death may take a matter of minutes. In comparison to a heart attack, SCA may occur without any warning and instant intervention is required.
This is where AED machines will come in to save lives.
An AED monitors irregular heart rates and provides a shock to the heart in order to resume normal rate. AED application, together with CPR, can have a significant positive impact on the survival rate.
