Study Notes
Hypertension
- A chronic condition affecting millions worldwide.
- Characterized by consistently high blood pressure in arteries.
- Places strain on the heart and blood vessels.
- Often called the "Silent Killer".
- Typically doesn't cause noticeable symptoms.
Blood Pressure
- The force exerted by blood against artery walls as the heart pumps.
- Measured in millimeters of mercury (mmHg).
- Systolic Pressure: The top number, representing pressure when the heart beats.
- Diastolic Pressure: The bottom number, representing pressure when the heart rests between beats.
Types of Hypertension
- Primary Hypertension: The most common type, accounting for 90-95% of cases.
- The cause is unknown but is linked to a combination of lifestyle and genetic factors.
- Secondary Hypertension: Caused by an underlying medical condition - such as kidney disease, thyroid problems, or certain medications.
Diagnosis
- Normal: Less than 120/80 mmHg.
- Elevated: 120/80 mmHg and above.
- Stage 1 Hypertension: 130-139 mmHg (systolic) & 80-89 mmHg (diastolic).
- Stage 2 Hypertension: 140 mmHg or higher (systolic) & 90mmHg or higher (diastolic).
- Malignant Hypertension: A constant increase in blood pressure.
Risk Factors
- Age
- Race: Common in Black individuals.
- Family History
- Obesity or being overweight.
- Lack of Exercise.
- Tobacco Use.
- High Salt Intake.
Treatment
- Lifestyle Changes:
- Weight Management.
- Healthy Diet: DASH Diet, rich in fruits, whole grains, low-fat dairy.
- Sodium Reduction: Less than 1,500 mg per day.
- Regular Exercise: 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity per week.
- Alcohol Moderation: 1 drink per day for women, 2 drinks per day for men.
- Stress Management: Meditation, yoga, deep breathing.
- Medications:
- ACE Inhibitors.
- Angiotensin II Receptor Blockers (ARBs).
- Calcium Channel Blockers.
- Diuretics.
- Beta Blockers.
Endocarditis
- A serious, potentially life-threatening infection.
- Inflames the inner lining of the heart - chambers and valves.
- This lining is called the endocardium.
Causes and Pathophysiology
- Primarily caused by infection – typically bacterial, fungal, or other germs.
- Reduction in blood flow can cause chest pain, shortness of breath, and other symptoms.
Symptoms
- Chest pain.
- Pain that spreads to shoulders, arms, upper belly, back, neck or jaw.
- Nausea/Vomiting.
- Indigestion.
- Shortness of breath.
- Sudden, heavy sweating.
- Racing heartbeat.
- Feeling lightheaded/dizzy.
- Fainting.
- Unusual fatigue.
- Abscesses: Pockets of pus can form around valves.
- Heart failure.
- Sepsis.
Diagnosis
- Electrocardiogram (ECG).
- Blood Tests.
- Chest X-ray.
- Echocardiogram.
- Cardiac catheterization – threading a thin tube (catheter) into a blood vessel in the arm or leg to reach the heart.
Treatment
- Medications:
- Aspirin: To prevent blood clot formation.
- Nitroglycerin: To dilate blood vessels.
- Beta-Blockers: To help slow heart rate and lower blood pressure.
- ACE Inhibitors: To lower blood pressure and protect the heart.
- Statins: To help lower cholesterol levels.
Types of ACS
- Unstable Angina: Blood flow to the heart is reduced but not enough to cause damage to the heart muscle. Often described as "chest pain/discomfort".
- Non-ST Elevation Myocardial Infarction (NSTEMI): A heart attack where blood flow to the heart is partially blocked, causing damage to the heart muscle. Can be detected through blood tests, but not always through ECG.
- ST Elevation Myocardial Infarction (STEMI): A severe heart attack where blood flow to the heart is completely blocked, causing significant damage to the heart muscle. Can be detected through both blood tests and ECG.
Causes of ACS
- Buildup of fatty deposits (plaque) in the coronary arteries – the blood vessels that supply blood to the heart.
- When this plaque ruptures, a blood clot forms, blocking blood flow to the heart muscle.
Procedures
- Percutaneous Coronary Intervention (PCI): A catheter is used to insert a stent into the blocked coronary artery, opening it and restoring blood flow.
- Coronary Artery Bypass Surgery (CABG): Grafting a healthy blood vessel from another part of the body to bypass a blocked coronary artery.
Prevention
- Lifestyle Changes:
- Quit smoking.
- Eat a healthy diet.
- Maintain a healthy weight.
- Get regular exercise.
- Manage stress.
- Control underlying conditions – diabetes, high blood pressure, high cholesterol.
Vascular Diseases
- Encompass a wide range of conditions that affect the body's network of blood vessels, also known as the circulatory system.
- Vessels are responsible for transporting oxygen-rich blood from the heart to the body's tissues and organs.
- They also carry waste products back to the heart.
- If compromised, vascular diseases can lead to various health problems, ranging from mild discomfort to life-threatening complications.
Types of Vascular Diseases
- Arterial Diseases: Affect arteries, which carry blood away from the heart.
-
Common Arterial Diseases:
- Atherosclerosis: The most common type of vascular disease characterized by the buildup of plaque (fatty deposits) inside arteries. Narrows arteries, restricting blood flow and increasing the risk of blood clots.
- Peripheral Artery Disease (PAD): Affects arteries in the legs and feet, causing pain, cramping, numbness, and coldness in extremities. In severe cases, PAD can lead to tissue death (gangrene) and amputation.
- Carotid Artery Disease: Affects arteries in the neck, supplying blood to the brain. Plaque buildup could lead to a stroke or transient ischemic attack (TIA) – "mini stroke".
- Aortic Aneurysm: A bulge or weakening in the aorta, the main artery that carries blood from the heart.
- Buerger's Disease: A rare condition primarily affecting small and medium-sized arteries and veins in the arms and legs, causing inflammation and blood clots. Often linked to "tobacco use".
- Venous Diseases: Affect veins, which carry blood back to the heart.
-
Common Venous Diseases:
- Deep Vein Thrombosis (DVT): A blood clot forming in a deep vein, usually in the legs. If the clot breaks loose and travels to the lungs, it can cause a pulmonary embolism.
- Chronic Venous Insufficiency (CVI): Valves in veins are damaged, preventing blood from flowing back effectively to the heart. It can lead to swelling, pain, and skin ulcers in the legs.
- Varicose Veins: Swollen, twisted veins visible under the skin. Caused by weakened valves in veins.
- Spider Veins: Smaller, red/purple veins, often seen in the legs or face. Caused by dilated capillaries.
- Lymphatic Diseases: Affect the lymphatic system – a network of vessels and nodes that help filter waste and fight infection.
-
Common Lymphatic Disease:
- Lymphedema: Abnormal buildup of fluid in tissues – often in the arms or legs. Caused by damage or blockage of lymphatic vessels.
Risk Factors
- Age
- Family History
- Lifestyle Factors: Smoking, lack of physical activity, unhealthy diet, obesity.
- Medical Conditions: Diabetes, high cholesterol, hypertension, certain autoimmune diseases.
Symptoms
- Pain: Mild discomfort to severe pain, especially during physical activity.
Treatment
- Lifestyle Changes:
- Quit smoking.
- Maintain a healthy weight.
- Eat a heart-healthy diet.
- Engage in regular physical activity.
- Medications:
- Blood pressure medications.
- Cholesterol-lowering drugs.
- Blood thinners.
- Medications to dilate blood vessels.
- Procedures:
- Angioplasty: Widening a narrowed artery.
- Stenting: Inserting a small tube to keep an artery open.
- Surgery: Bypassing a blocked artery.
