• Heredity, if the parents suffer then the incidence of coronary artery disease in children is higher than others.
• Smoking
• High blood pressure and diabetes
• Increased body fat (cholesterol)
• Lack of exercise
• Mental stress

These are symptoms of obstruction in the arteries supplying blood to the heart. After a little exercise or walking, symptoms such as chest pain, pounding of the heart, difficulty breathing, and sweating may occur. As the obstruction in the blood vessels increases, the blood supply to the heart cells decreases, and the severity of the above symptoms increases. When the disease becomes serious, the above symptoms appear after a short walk in the patient, even without any movement. When a heart attack occurs, there is severe chest pain, a feeling of tightness or pressure in the chest. The pain may start in the chest and radiate to the left or right arm, shoulder, neck, jaw, or back. The patient has trouble breathing and sweats profusely. Sometimes vomiting also occurs, and the patient becomes unconscious. In such a situation, if the patient does not receive proper medical treatment on time, the rate of death of the patient is high. Pain and above symptoms are less or absent in diabetic patients. Therefore, it is advisable for diabetic patients to take extra care of their heart. The incidence of heart attacks is higher in the winter season, and the incidence of early morning attacks has been found to be higher.

Before a heart attack occurs, many patients experience symptoms of cardiovascular disease. These symptoms may include central chest pain, chest pressure, and sensations resembling heartburn. In such emergencies, the initial recommended remedy is often a nitrate pill, such as nitroglycerin. Nitroglycerin acts as a vasodilator, improving blood flow by dilating blood vessels and reducing strain on the heart.

• In case of heart pain, this pill should be kept under the tongue and the patient should be kept lying down after the onset of pain. Minimum movement should be allowed. Refer to specialist for further advice.
• Along with this pill, one aspirin tablet should be crushed and mixed with water and given immediately.
• If available, provide oxygen using a cylinder and mask.
• Check pulse and purity. If it is not clear, call someone for help as artificial cardiopulmonary resuscitation may be required.
• Take to hospital by ambulance. Some cities have a dedicated cardiac ambulance for heart patients.
• Call the concerned medical specialist and give an opinion. If the patient's name and address are not known, find out and inform relatives and friends. Also inquire about medical insurance.
