What is the definition of Blood Pressure?
BP is the force of blood as it pushes against the arteries as they carry blood from your heart to nourish your body.
How is BP measured?
BP is measured in units of mercury (mmHg) using a stethoscope and inflatable cuff or an automated machine.
What is Systolic BP measurement?
Systolic BP measurement is the top number - is the pressure in arteries when your heart beats.
What is the Diastolic measurement?
Diastolic BP - is the bottom number - is the pressure in your arteries when your heart rests.
What is normal blood pressure according to the 2017 CDC guidelines?
<120/<80
What is Prehypertension blood pressure according to the CDC 2017 guidelines?
120-129/<80. Considered Elevated and at risk for hypertension.
What is Hypertension Blood pressure range according to the CDC 2017 guidelines?
> =130/>=80
What is hypertension (Silent Killer).
Hardness and narrowing of the arteries (Arteriosclerosis) because of a buildup of plaque and possible blood clots, which makes the heart work harder and decreases blood flow to the heart.
What are the risks of hypertension? (5)
- Transient Ischemic Attacks - mini-stroke.
- Stroke (Brain Attack) - Burst or blocked artery in the brain.
- Heart Failure.
- Heart Attack - CAD
- Kidney disease - increased pressure in kidneys damages tissue. Kidneys help regulate blood pressure.
What are the condition or risks for developing hypertension?
- Prehypertension
- Diabetes
What are behaviors that can lead to hypertension? (5)
- Unhealthy diet (high salt intake, not enough potassium)
- Inactivity
- Obesity
- High Alcohol Intake - women 1 during a day, men - 2 drinks a day.
- Tobacco/Smoking
What other factors can lead to hypertension?
- Other family members with hypertension.
- Older Age
- African American
What 3 tests are used to diagnose cardiovascular disease or Coronary Artery Disease?
- BP
- Cholesterol
- Blood glucose level.
What other tests are used to diagnose those at High Risk for heart disease or already having symptoms? (6)
- EKG/ECG
- Echocardiogram
- Exercise Stress Test
- Chest X-Ray
- Cardiac Catheterization.
- Coronary Angiogram
What is an EKG/ECG?
Electrocardiogram - measures electrical activity, rate, and regularity of the heartbeat.
What is an Echocardiogram?
Uses ultrasound to create a picture of the heart.
What is an echocardiogram?
Uses ultrasound to create a picture of the heart.
What is an exercise stress test?
Measures heart rate while walking on a treadmill.
What is Cardiac Catheterization?
Checks the inside of arteries for blockage by inserting a thin flexible tube through an artery.
What is a Coronary Angiogram?
Monitors blockage and flow of blood through coronary arteries using x-rays to detect dye injected via cardiac catheterization.
What is CAD an acronym for?
Cardiovascular disease. Cardio - Heart, vascular arteries.
What does Cardiovascular Disease affect?
Cardiovascular disease affects the blood vessels of the heart and body. Cardiovascular disease is the most common type of heart disease in the United States.
Plaque builds up in the walls of the coronary and other arteries.
The inside of the arteries narrow over time (atherosclerosis), which can partially or totally block blood flow.
CAD can weaken the heart muscle. This may lead to heart failure - the heart can’t pump blood in the way it should. CAD can also lead to an irregular heartbeat or an arrythmia can develop.
When your heart doesn’t get enough blood, chest pain or discomfort, called Angina can develop.
What is Plaque?
Plaque is made up of deposits of cholesterol and other substances.
What is Atherosclerosis?
Plaque builds up in the arteries over time and causes the narrowing of the arteries. Atherosclerosis makes it harder for blood to flow through your body.
What does the acronym F.A.S.T. stand for?
Used by anyone to quickly help diagnose a stroke.
F - Face - asks the person to smile. Does one side of the face drop?
A - Arms - Ask the person to raise both arms. Does one arm drift downward?
S - Speech - Ask the person to repeat a simple phrase. Is the speech slurred or strange?
T - Time: If you see any of these signs call 911 immediately.
What pre-existing conditions increase the chance of a stroke? (5)
- Hypertension
- High cholesterol
- Diabetes
- Sickle Cell disease
- A previous stroke or TIA
What behaviors are risk factors for a stroke? (5)
- Unhealthy Diet
- Physical inactivity
- Obesity
- High Alcohol Intake
- Tobacco Smoking.
What other factors, including family history, are conducive to a stroke? (4).
- Genetics
- Older Age
- Female
- Race/Ethniticity.
Blacks, Hispanics, American Indians, and Alaskan natives are more likely to have a stroke than non-hispanic whites or Asians.
African Americans have 2x as many strokes as whites and are twice as likely to die from them.
What are the 5 major signs of a Heart Attack?
- Chest pain or discomfort.
- Nausea, feeling lightheaded or unusually tired.
- Pain or discomfort in the jaw, neck, or back.
- Pain or discomfort in the arm or shoulder.
- Shortness of breath.
What is a stroke?
When the flow of blood in the brain is disrupted, brain cells start to die immediately because they do not get enough oxygen.
What are the 2 types of strokes?
- Ischemic Stroke
- Hemorrhagic Stroke
What is an Ischemic Stroke?
Blood clots or plaque blocks blood vessels in or to the brain.
What is a Hemorrhagic Stroke?
A blood vessel bursts in the brain and damages the surrounding brain tissue.
What are the signs of a stroke? (6)
- Numbness or weakness in the face, arms, or legs, especially on one side of the body.
- Confusion, trouble speaking, or difficulty understanding speech.
- Trouble seeing in one or both eyes.
- Trouble walking, dizziness, loss of balance, or lack of coordination.
- Severe headache with no known cause.
- If symptoms go away after a few moments, it may be a TIA.
What is Metabolic Syndrome?
Metabolic syndrome is a cluster of conditions that occur together, increasing your risk of heart disease, stroke and type 2 diabetes.
Three or more of the following conditions that increase the risk include:
1. increased blood pressure.
2. high blood sugar
3. excess body fat around the waist.
4. abnormal cholesterol or triglyceride levels.
5. Or taking any medicine to treat the above.
People at greater risk for Metabolic Syndrome have what underlying conditions?
- Abdominal Obesity
- An inactive lifestyle
- Insulin Resistance
- Race/Ethnicity - Mexican Americans have the highest rates compared to black or whites.
- Diabetes or a sibling or parent with diabetes.
- Women, especially those with polycystic ovarian syndrome (PCOS).
