Study Notes
Study Notes
Systole and Diastole
- Systole is the phase of the heart cycle where the heart chambers decrease in size to eject blood into circulation.
- Diastole refers to the relaxation phase of the heart, where the chambers fill with blood.
Point of Maximum Impulse (PMI)
- The PMI is best palpated at the left midclavicular line, specifically at the fifth intercostal space.
- This area corresponds to the location of the left ventricle, responsible for the apical heartbeat.
Pulse Pressure Calculation
- Pulse pressure is determined by subtracting diastolic pressure from systolic pressure.
- For a blood pressure of 122/76, the pulse pressure is 46 mm Hg.
Central Venous Pressure (CVP)
- A low CVP often indicates hypovolemia, which suggests reduced right ventricular preload.
- CVP provides insight into heart function and volume status.
Heart Sounds
- An audible S3 heart sound is considered normal in individuals up to about 35-40 years old; it is categorized as a physiologic S3.
Coronary Artery Disease and Heart Rate
- Increased heart rate during physical activity in patients with CAD may lead to myocardial ischemia due to reduced coronary perfusion.
Cardiac Output Influences
- Cardiac output can be compromised by a low heart rate; for instance, a heart rate of 54 bpm can reduce overall output.
Orthostatic Blood Pressure
- Significant drops in blood pressure upon changing positions (e.g., from supine to standing) may indicate orthostatic hypotension, which poses a risk for falls.
CVP Monitoring
- An increasing CVP can be indicative of hypervolemia or conditions like heart failure due to decreased myocardial contractility.
Pulmonary Artery Pressure Monitoring
- This monitoring assesses left ventricular function and evaluates the body's response to fluid and medications.
Cardiac Conduction System
- The normal sequence of cardiac electrical conduction is SA node → AV node → Bundle of His → Purkinje fibers.
Myocardial Infarction
- Damage to the myocardium impacts the heart's pumping ability; this layer of muscle is critical for cardiac function.
Afterload and Stroke Volume
- Increased afterload, often due to arterial vasoconstriction, negatively affects stroke volume, reducing cardiac output.
Cardiac Catheterization Purpose
- It is primarily used to evaluate the patency of coronary arteries to decide on potential revascularization.
Monitoring Cardiac Function
- Continuous ECG monitoring is critical in emergency settings for clients displaying signs of potential cardiac events.
Falls & Orthostatic Hypotension
- Patients with significant blood pressure drops upon standing are at increased risk for falls due to dizziness.
B-type Natriuretic Peptide (BNP)
- Elevated BNP levels in older adults suggest potential heart failure, serving both diagnostic and prognostic roles.
Lipid Profile Testing
- A lipid profile should be drawn after a 12-hour fast to ensure accurate cholesterol level assessment.
Aspirin for Cardiovascular Health
- Daily aspirin use is recommended to prevent blockages that may lead to chest pain or myocardial infarction.
High Sensitivity C-reactive Protein (hs-CRP)
- This test evaluates systemic inflammation, which is heavily implicated in atherosclerosis development.
Transthoracic Echocardiography
- This noninvasive test provides a profile of heart function without entering the body, minimizing discomfort.
Preparing for Cardiac CT
- Establishing peripheral IV access is necessary for administering contrast during cardiovascular CT scans.
Exercise Stress Test Protocol
- If a patient experiences chest pain before reaching target heart rate, the test should be stopped for close monitoring.
Troponin Levels in Angina
- Elevated troponin I levels accurately indicate myocardial injury and are measured shortly after such injuries occur.
Cholesterol Levels and CAD Risk
- Increased LDL and decreased HDL levels correlate with a higher risk of coronary artery disease.
Angina Characteristics
- Chest pain following physical exertion is a key indicator of angina.
Client Education in CAD
- Recognizing symptoms of acute cardiac problems by the patient and family members is crucial for timely intervention during emergencies.
