A Heart attack, also called a myocardial infarction(MI), occurs when the blood supply to a part of the heart is blocked.

Medications of heart attack

1. Use of aspirin

2. Use of thrombolytics

3. Nitroglycerin- used to treat chest pain , can help improve blood flow to the heart by widening(dilating) of the blood vessels.

4. Beta blockers- helps to relax heart muscles, slow your heart beat and decrease blood pressure.

Surgical Procedures:

1. Coronary angioplasty and stenting

2. Coronary artery bypass...

The causes of drug abuse are:
1. Curiosity

2. Peer group pressure

3. Excitement

4. Persistent use to get relief from pain

5. Family history of consumption of drugs

6. To overcome frustration and depression

7. Desire to do more physical or mental work.

The differences between 'J' shaped curve and 'S' shaped curve are:

'Malthus theory" is based on following facts:

1. The means of subsistence (mean of supporting life, like food) grows only arithmetically while unchecked population grows geometrically.

2. The rapid growth of population creates imbalances with the environment.

3. The imbalances at higher degree causes malnutrition, hunger, spread of diseases, droughts, war, etc. which ultimately reduce the population up to the level of the availability of substituent ( food etc).

Heart disease refers to a range of conditions that affect the heart and its functioning. Here are some common types of heart diseases:

1. Coronary Artery Disease (CAD): CAD is the most prevalent type of heart disease. It occurs when the coronary arteries that supply blood to the heart become narrowed or blocked due to the buildup of plaque. This can lead to chest pain (angina), heart attacks, and other serious complications.

2. Hypertension (High Blood Pressure): High blood pressure occurs when...

Drug addiction, also known as substance use disorder, refers to a chronic and relapsing condition characterized by the compulsive use of drugs despite negative consequences. It is a complex health issue that involves both physical and psychological dependence on a substance. Drug addiction can have severe effects on an individual's health, relationships, and overall well-being.

Causes of Drug Addiction:

1. Biological Factors: Genetic predisposition and variations in brain chemistry can make...

A heart attack, also known as myocardial infarction, occurs when there is a blockage or reduced blood flow to the heart muscle, leading to damage or death of the heart tissue. The primary cause of a heart attack is usually the formation of a blood clot within one of the coronary arteries, which supply oxygen-rich blood to the heart. Here are the main causes and signs of a heart attack:

Causes of a Heart Attack:

1. Coronary Artery Disease (CAD): The most common cause of a heart attack is CAD,...

Population explosion refers to a rapid and dramatic increase in the size of the human population over a relatively short period. It occurs when the birth rate significantly exceeds the death rate, leading to exponential population growth. This phenomenon has important implications for resources, environment, social systems, and overall sustainability.

Causes of Population Growth:

1. High Fertility Rates: A major factor contributing to population growth is high fertility rates, particularly in...

The J-shaped and S-shaped population growth curves are two different patterns that represent how a population's size changes over time.

1. J-Shaped Population Growth Curve:The J-shaped curve, also known as exponential growth, is characterized by rapid and unrestricted population growth. In this pattern, the population size increases at an accelerating rate over time, resulting in a curve that resembles the letter "J." The J-shaped curve occurs when there are abundant resources available for...
