Study Notes
Circulatory Functions Overview
- Review of anatomy and physiology of the circulatory system is crucial for assessing and managing patients with cardiovascular disorders and peripheral circulation problems.
- Understanding heart structure and function is essential for developing cardiovascular assessment skills.
- The heart is a hollow muscular organ located in the mediastinum of the thorax, resting on the diaphragm.
- It weighs approximately 300 grams (10.6 oz).
- Age, gender, body weight, physical conditioning, and pre-existing heart disease influence heart size and weight.
Heart Location and Position
- Visual aids (images) show the heart's location within the thorax in relation to the lungs and diaphragm.
Heart Anatomy
- Diagrams (images) illustrating the heart's chambers (right atrium, left atrium, right ventricle, left ventricle), valves (tricuspid, mitral, aortic, pulmonary), and major vessels (aorta, vena cava, pulmonary arteries, pulmonary veins) are presented.
Anatomy of the Heart (detailed diagram)
- Listing of anatomical features (valves, arteries, veins) on diagrams. Specific anatomical parts are labeled.
Layers of the Heart Wall
- The heart wall is composed of three layers:
- Epicardium (outer layer)
- Myocardium (middle, muscular layer)
- Endocardium (inner layer)
Heart Anatomy
- Detailed diagram of the heart identifying key anatomical parts.
Health History
- Signs and symptoms of CVD (Cardiovascular Disease) are associated with dysrhythmias, conduction problems, structural, infectious, and inflammatory heart disorders, and complications like heart failure (HF) and cardiogenic shock.
- Nurses must be adept at recognizing the signs and symptoms of these conditions for timely and lifesaving care.
- Important details for assessing pain (location, severity, duration) in CVD patients are emphasized.
- Presenting conditions (e.g., acute coronary syndrome) often involve multiple conditions requiring comprehensive assessment.
Signs and Symptoms of CVD
- Chest pain (angina pectoris, acute cardiac syndrome, valvular heart disease) location, severity, and duration are assessed to determine seriousness.
- Clinicians should monitor for pain originating from various sources (e.g., myocardial ischemia or shortness of breath).
Pain or Discomfort in Other Areas
- Pain or discomfort in other body areas (e.g., arms, back, jaw, stomach) is associated with acute coronary syndrome, cardiogenic shock, heart failure, and valvular heart disease.
- Patients experiencing these conditions are assessed for palpitations, edema, enlarged spleen or liver, ascites (fluid buildup in the abdomen), or unusual tiredness.
Past Medical History, and Family History
- Patient's understanding of personal risk factors contributing to peripheral vascular, cerebrovascular, and CAD (coronary artery disease) is assessed.
- Risk factors, including increasing age, sex, smoking, hypertension, high cholesterol, diabetes, obesity, and physical inactivity are relevant.
Heredity and Modifiable Risk Factors
- Heredity is usually not modifiable, however, risk factors such as smoking, hypertension, high cholesterol, diabetes, obesity, physical inactivity and medications can be modified.
Patient Questions (Assessment)
- Nurses should question patients about their health status (past year, 5 years), healthcare providers, health concerns, family history of genetic disorders associated with cardiovascular disease, and personal health practices.
Medications
- Obtaining the complete list of medications—including multivitamins and herbal preparations—and over-the-counter medications is crucial for comprehensive assessment.
Nutrition
- The weight and size of the heart are influenced by factors like age, gender, body weight, physical activity, and heart disease.
- Diets restricting sodium, fat, cholesterol, and calories may be prescribed to manage heart-related conditions.
- Assessment typically involves information on current weight, height, BMI, waist measurement, results of blood glucose levels, and glycosylated hemoglobin.
- Nutritional habits and meal preparation details should be noted.
Elimination
- Bowel patterns (bloating, gas, constipation, upset stomach, heartburn, loss of appetite, vomiting, and nausea) may indicate various underlying physiological issues. Blood tests are vital for patients taking blood thinning medications.
Activity Level
- Changes in activity level and whether those changes relate to activity-induced angina, shortness of breath, or myocardial ischemia are evaluated.
- Assessments include home architectural barriers, and participation in cardiac rehabilitation activities.
Sleep and Rest
- Worsening cardiac conditions (e.g., heart failure) can manifest through sleep-related problems such as orthopnea, paroxysmal nocturnal dyspnea (awakening with shortness of breath), snoring, frequent awakenings, headaches, and daytime sleepiness. This requires evaluation of sleep disordered breathing (SDB) patterns.
Self-Perception and Self-Concept
- Chronic illnesses (e.g., heart failure) or acute conditions (e.g., myocardial infarction) can affect self-perception and self-concept.
- Patient's perceptions regarding their illness are critical determinants of adherence to self-care recommendations.
Roles and Responsibilities
- An assessment of the patient's roles, responsibilities, and family relationships is conducted, including living situation and caregiver, healthcare management methods, and financial support systems.
Sexuality and Reproduction
- Sexual dysfunction occurs twice as often in CVD patients as in the general population.
- Physical activities associated with sexual relations can trigger heart attacks or sudden death. Coping and stress tolerance are important for assessments, including observations of depression, feelings of worthlessness, guilt, sleep disturbances, and stress-induced hormonal changes.
Physical Assessment
- Physical assessment is conducted to confirm information from health history, establish baseline data, and evaluate patient response to treatment.
- Key cardiovascular components to assess include cardiac output, pulse pressure, displacement, heart sounds, arterial-ventricular filling pressures (e.g., elevated jugular venous distension), peripheral edema, ascites, crackles, and postural changes in blood pressure.
Blood Pressure
- Normal systolic BP is less than 120 mmHg, and normal diastolic BP is less than 80 mmHg.
- Consistently high systolic pressure (above 140 mmHg) or diastolic pressure (above 90 mmHg) is considered high.
- Abnormally low systolic and diastolic blood pressure is regarded as hypotension. Monitoring for hypotension is important due to lightheadedness or fainting risks.
Pulse Pressure
- Pulse pressure is the difference between systolic and diastolic blood pressures.
- A normal pulse pressure range is 30-40 mmHg, reflecting stroke volume, ejection velocity, and systemic vascular resistance.
- Low pulse pressure (below 30 mmHg) indicates compromised cardiac output and warrants further evaluation.
Postural (Orthostatic) Blood Pressure Changes
- Gravitational shifts in blood distribution to the lower extremities and gastrointestinal system upon standing can cause postural hypotension and should be monitored (at least 20 mmHg decrease in systolic BP or 10 mmHg in diastolic BP).
Arterial Pulses
- Palpation of arterial pulses (e.g., rate, rhythm, amplitude, and contour) is used to assess flow.
- Jugular venous pulsation observation reflects central venous pressure (CVP) assessment, which helps determine right-sided heart function.
- Increased CVP may indicate right-sided congestive heart failure (CHF).
Heart Inspection and Palpation
- A standard systematic approach is utilized for inspecting and palpating the precordium, using specific anatomical landmarks (e.g., aortic, pulmonic, Erb point, tricuspid, mitral, and epigastric areas).
Heart Auscultation
- Auscultation involves listening for normal and abnormal heart sounds to further evaluate cardiac function.
Assessment of Other Systems (e.g., Lungs)
- Pulmonary assessment—including auscultation—is used to identify abnormalities indicative of heart conditions like pulmonary edema, haemoptysis, wheezes or crackles.
Abodmen
- For patients with cardiovascular disease, abdominal examination including assessing abdominal distention (possible ascites), evaluating hepatoyugular reflux, bladder distension (urine output), and evaluating reduced renal output is important.
Gerontological Considerations
- During assessments of older patients, consider potential differences in peripheral pulses (due to decreased skin elasticity), chest shape changes affecting cardiac palpation, associated conditions (systolic hypertension, postural orthostatic hypotension), and fall risk.
Diagnostic Evaluation
- Various diagnostic studies may be performed in patients with cardiovascular conditions, such as blood tests, 12-lead ECG, radiological imaging (chest X-ray).
- Nurses should instruct patients about the purpose of these evaluations, potential side effects, and expectations.
Laboratory Tests
- Blood samples are sent for various laboratory tests to assist diagnosis, screen for risk factors related to CVD, assess abnormalities impacting prognosis, and establish baseline values.
- Normal values may differ across laboratories and institutions.
Cardiac Biomarker Analysis
- Evaluating cardiac biomarkers (e.g., lipid profiles, brain natriuretic peptide) assists in diagnosing conditions like myocardial infarction (MI) and determining the risk of coronary artery disease (CAD).
- Assessing biomarker levels can inform monitoring and prognosis in heart failure conditions.
C-reactive Protein and Homocysteine
- C-reactive protein (CRP) and homocysteine are evaluated as markers of inflammation and cardiovascular risk, as they have been linked to atherosclerosis, stroke risk, and peripheral vascular disease.
Diagnostic Studies (e.g., X-ray, ECG)
- Types of diagnostic procedures such as chest X-ray and fluoroscopy, electrocardiography (ECG) and continuous monitoring are discussed. Imaging, or electrocardiographic tests that identify cardiac abnormalities, are used for diagnosis.
Cardiovascular Monitoring Devices
- Various instruments and technology used for monitoring heart rhythm and activity include hard-wired cardiac monitors, telemetry, ambulatory ECG devices, continuous monitors, cardiac event monitors, and implantable devices.
Computed Tomography, Angiograms, Catheterization, and Electrophysiology
- Advanced imaging techniques (e.g., computed tomography (CT), magnetic resonance angiography (MRA)), cardiac catheterization, and electrophysiological testing are methods used to assess cardiovascular conditions.
Peripheral Arterial Occlusive Disease (PAD)
