2.67: Understand How Factors May Increase the Risk of Developing Coronary Heart Disease

CORONARY HEART DISEASE: Blockage of Coronary Artery by Fat globules (forming plaques), causing insufficient Oxygen transport in blood leading to increased anaerobic respiration (due to lack of Oxygen)
s

• Increase in anaerobic respiration causes build-up of Lactic acid which creates acidic environment for enzymes to denature, hence causing strokes

FACTORS THAT INCREASE RISK OF CORONARY HEART DISEASE:

FACTOR	EXPLANATION
POOR DIET	Diets rich in Saturated Fats, Salts and Alcohol increases the presence of Cholesterol in diet, increasing the risk of Coronary Heart Disease (CHD)
STRESS	Stress stimulates the secretion of Hormones that increases blood pressure, therefore increasing the risk of the buildup of Fatty plaques to cause Coronary Heart Disease (CHD)
SMOKING	Nicotine in cigarettes causes vasoconstriction - the narrowing of blood vessels, increasing the risk of the buildup of Fatty plaques to cause Coronary Heart Disease (CHD)
