Study Notes
ST-Segment Elevation Myocardial Infarction (STEMI)
- ST-segment elevation greater than 0.1 mV in two contiguous precordial leads indicates a STEMI.
- Hallmark of a STEMI on an ECG is ST-segment elevation.
Coronary Artery Disease (CAD) Risk Factors
-
Risk factors associated with coronary artery disease include:
- Age
- Smoking
- Diabetes
- High blood pressure
- High cholesterol
Acute Coronary Syndrome (ACS)
- Symptom often associated with acute coronary syndrome when NTG does not relieve chest pain: Acute myocardial infarction (MI).
- Non ST segment elevation myocardial infarction (NSTEMI): A classification of ACS where there is myocardial damage but no ST segment elevation.
Cardiac Health and Assessment
- Patient with hypertrophic cardiomyopathy is at the highest risk for sudden cardiac death.
- Electrocardiogram (ECG) is the best assessment to diagnose dysrhythmias.
- A common consequence of advanced coronary artery disease is heart failure.
- Angina pectoris indicates: Myocardial ischemia, meaning insufficient blood supply to the heart muscle.
Unstable Angina
- ECG finding important to note in patients with unstable angina: ST segment depression or T wave inversion.
- Essential management approach for a patient with suspected MI: Immediate evaluation and treatment in a cardiac care unit.
Coronary Artery Disease Pathology
- Significance of fat streaks in young adults: Early stages of atherosclerosis, often found in coronary arteries, may progress to more significant plaque buildup.
- Normal finding in healthy children: Absence of significant coronary artery disease.
Myocardial Ischemia and Atherosclerosis
- Key symptom of myocardial ischemia: Chest pain.
- Atherosclerotic plaque that is increased in size but does not occlude blood flow: A vulnerable plaque, prone to rupture and potential for thrombosis.
Managing Coronary Artery Disease
-
Preventive measures for managing coronary artery disease: Lifestyle changes such as:
- Quitting smoking
- Maintaining a healthy weight
- Regular exercise
- Controlling blood pressure
- Managing cholesterol levels
- Elevated Troponin I or T in a patient suspected of having a STEMI: Indicates myocardial damage.
Heart Failure and Clinical Manifestations
- Sign most closely associated with pulmonary edema in heart failure: Crackles (rales) in lung auscultation.
- Primary assessment focus for a patient experiencing a suspected MI: Cardiovascular status.
- Characteristic heart sound indicating heart failure: S3 heart sound.
-
Additional information needed for cardiac risk assessment:
- Family history of heart disease
- Current medications
- Lifestyle habits
Clinical Assessment and Complications
- Abnormal finding that might suggest shock or poor perfusion: Cool, clammy skin.
- Finding indicating a complication in a patient receiving fibrinolytic therapy: Bleeding.
- Crackles and wheezes during lung auscultation: May indicate pulmonary edema or pneumonia.
