Study Notes
Cardiovascular Disease
- Cardiovascular disease is a group of diseases affecting the heart and blood vessels.
- A person may be symptomatic or asymptomatic.
- Different causes exist for specific types of cardiovascular diseases.
-
Risk factors:
- High blood pressure (hypertension)
- High cholesterol (hyperlipidemia)
- Tobacco use (including vaping)
- Type 2 diabetes
- Family history of heart disease
- Lack of physical activity
- Excess weight or obesity
- Diet high in sodium, sugar and fat
- Overuse of alcohol
- Misuse of prescription or recreational drugs
- Preeclampsia or toxemia
- Gestational diabetes
- Chronic inflammatory or autoimmune conditions
- Chronic kidney disease
Symptoms of Cardiovascular Disease
- Symptoms vary depending on the cause, and older adults or people assigned female at birth may experience more subtle symptoms.
-
Heart Issues:
- Chest pain (angina)
- Chest pressure, heaviness or discomfort
- Shortness of breath (dyspnea)
- Dizziness or fainting
- Fatigue or exhaustion
-
Blood vessel blockages:
- Pain or cramps in the legs when walking
- Leg sores that aren't healing
- Cool or red skin on the legs
- Swelling in the legs
- Numbness in the face or a limb (may be on one side)
- Difficulty with talking, seeing or walking
Congenital Heart Disease (CHD)
- Two main groups: cyanotic congenital heart disease and acyanotic congenital heart disease.
-
Cyanotic CHD involves heart defects reducing oxygen delivered to the body.
- Examples:
- Left heart obstructive lesions
- Right heart obstructive lesions
- Mixing lesions
- Examples:
-
Acyanotic CHD involves defects causing abnormal blood flow through the body.
- Examples:
- Hole in the heart
- Problem with the aorta
- Problem with the pulmonary artery
- Examples:
- CHD symptoms may appear at birth or later in life.
-
Symptoms:
- Cyanosis (blueish skin, lips or nails)
- Excessive sleepiness
- Fast breathing or trouble breathing
- Fatigue
- Tiredness or shortness of breath during exercise
- Heart murmur
- Poor blood circulation
- Weak pulse or pounding heartbeat
-
Symptoms:
Causes of CHD
- CHD occurs when the fetal heart doesn't develop correctly in the uterus.
- The cause is not fully understood but may be related to:
- Abnormal chromosomes or genetics
- Drinking or smoking during pregnancy
- Illnesses in the mother during pregnancy (diabetes, drug use, phenylketonuria, viral infection)
- Environmental exposures (secondhand smoke)
Diagnosis of CHD
- Tests for CHD may include:
- Physical exam
- Chest X-ray
- Electrocardiogram (EKG or ECG)
- Echocardiogram (echo)
- Heart catheterization
- Magnetic resonance imaging (MRI)
Management and Treatment of CHD
- Treatment may involve:
- Catheter procedure to place a plug into the defect
- Medications to improve heart function or manage blood pressure
- Nonsurgical procedure to close a defect using a closing device
- Oxygen therapy
- Prostaglandin E1
- Surgery to repair a defect, open blood flow, or redirect blood
- Heart transplant (in severe cases)
Prevention of CHD
- No proven strategies to prevent CHD.
- Avoid risk factors during pregnancy:
- Don't use recreational drugs
- Get all recommended screening tests
- Manage health conditions (diabetes, phenylketonuria)
- Stop smoking and avoid secondhand smoke
- Avoid alcohol
Heart Failure
- Occurs when the heart muscle doesn't pump blood as well as it should.
- Blood backs up, causing fluid buildup in the lungs, leading to shortness of breath.
- Sometimes called congestive heart failure.
Symptoms of Heart Failure
- Symptoms may develop slowly or suddenly.
- Shortness of breath with activity or when lying down
- Fatigue and weakness
- Swelling in the legs, ankles, and feet
- Rapid or irregular heartbeat
- Reduced ability to exercise
- Wheezing
- Persistent cough (may bring up white or pink mucus with blood)
- Swelling in the belly area
- Rapid weight gain
- Nausea and lack of appetite
- Difficulty concentrating or alertness
- Chest pain (if caused by a heart attack)
Causes of Heart Failure
- Caused by a weakened, damaged, or stiff heart.
- Heart muscle damage can be caused by:
- Certain infections
- Heavy alcohol use
- Illegal drug use
- Some chemotherapy medicines
- Genetics
-
Conditions that damage or weaken the heart:
- Coronary artery disease and heart attack (most common cause)
- High blood pressure
- Heart valve disease
- Inflammation of the heart muscle (myocarditis)
- Congenital heart defects
- Irregular heart rhythms (arrhythmias)
- Other diseases (diabetes, HIV, thyroid issues, iron/protein buildup)
Causes of Sudden Heart Failure
- Allergic reactions
- Widespread illness
- Blood clots in the lungs
- Severe infections
- Certain medications
- Viruses that attack the heart muscle
Types of Heart Failure
- Right-sided heart failure: affects the right ventricle; fluid may back up into the belly, legs, and feet, causing swelling.
- Left-sided heart failure: affects the left ventricle; fluid may back up in the lungs, causing shortness of breath.
Risk Factors of Heart Failure
- Factors that increase the risk of heart failure:
- Coronary artery disease
- Heart attack
- Heart valve disease
- High blood pressure
- Irregular heartbeats
- Very frequent and fast irregular heartbeats
