• Blood pressure is the force that blood exerts on the walls of a blood vessel. High blood pressure can injure blood vessel walls, leading to other cardiovascular diseases.
• Systolic pressure is the maximum blood pressure when the heart contracts. Diastolic pressure is the blood pressure between heart contractions.
• Blood pressures are cited in the form “Systolic pressure/Diastolic pressure.”
• Normal blood pressure is between 80/50 and 130/85.
• Atherosclerosis is a disease in which fatty materials build up on artery walls. This can block blood flow or release clots that cause strokes or heart attacks.
• Cholesterol is another type of lipid found in all human and animal tissues.
• Your body makes cholesterol. You also get cholesterol from foods such as meat, eggs, and dairy products.
• Cholesterol is necessary for certain essential functions in the body.
• Too much of certain types of cholesterol in your diet can cause deposits on blood vessel walls, increasing the risk of heart attack. (Atherosclerosis)
• Medical researchers aren't sure exactly how stress increases the risk of heart disease.
• Stress itself might be a risk factor, or it could be that high levels of stress make other risk factors worse (e.g. high blood pressure and high cholesterol)– Fight-or-flight response: For example, if you are under
stress, your blood pressure goes up, you may overeat, you may exercise less, and you may be more likely to smoke.
• Chronic stress exposes your body to unhealthy, persistently elevated levels of stress hormones like adrenaline and cortisol.
• Studies also link stress to changes in the way blood clots, which increases the risk of heart attack.
