DSA- Cardiac Clinical Medicine Part 1 Flashcards
What term is described as chest pain or pressure for at least 2 months’ duration that is precipitated by exertion or emotional stress and has not appreciably worsened?
Stable angina
What term is described as new onset angina, angina with minimal exertion, angina at rest, or angina
accelerating in frequency or severity?
How are the cardiac enzymes with this condition?
1) Unstable angina
2) Normal cardiac troponin levels
NSTEMI is defined by ST segment depression and/or T-wave inversions with?
Elevated cardiac troponin levels
STEMI is defined by ST segment elevation with?
Either abnormal cardiac enzymes, new LBBB or posterior MI
What is the leading cause of death in the U.S?
Coronary Artery Disease
What are some modifiable risk factors for CAD?
1) HTN
2) Hyperlipidemia
3) DM
4) Smoking
5) Diet
What are some non-modifiable risk factors for CAD?
1) Male sex
2) Age
3) Family history of CAD
4) Ethnicity
What makes up the hyperlipidemia seen with CAD?
1) Low HDL
2) High LDL
What are some non-traditional risk factors for CAD?
1) CKD
2) Proteinuria
3) Inflammatory states such as HIV and RA
Hyperlipidemia, hyperglycemia, hypertension, and other influences cause?
What does this cause?
1) Endothelial dysfunction
2) Platelet adhesion and recruitment of circulating monocytes and T cells
The recruitment of circulating monocytes and T cells, with subsequent cytokine and growth factor release from inflammatory cells leads to?
Smooth muscle cell migration and proliferation as well as further macrophage activation
What is the classic presentation for acute coronary syndrome?
1) Typical chest pain
2) Dyspnea
3) Nausea and vomiting
4) Diaphoresis
5) Fatigue
AMIs that are painless (silent) and/or have atypical symptoms are more common in what patients?
1) Elderly
2) Women
3) Diabetics
Angina pectoris chest pain has what 3 classic components?
What defines typical angina chest pain?
Atypical angina chest pain?
Non-angina chest pain?
1) Substernal chest pain or discomfort
2) Provoked by exertion or emotional stress
3) Relieved by rest and/or Nitroglycerin
1) Has all 3 components
2) Has 2 of the 3 components
3) Has ≤ 1 of the components
What should be the first test you perform on a patient when diagnosing CAD?
Resting ECG
Cardiac stress testing should only be done for patients with?
Patients with positive stress tests should proceed to?
1) Intermediate pretest probability of CAD
2) Invasive coronary angiography
If an exercise cardiac stress test can’t be performed what are other options?
1) Vasodilators
2) Inotropes and chronotropes
Which pharmacological cardiac stress test dilates the coronary arteries similar to exercise?
Which increases myocardial oxygen demand by increasing heart rate and contractility
1) Vasodilators
2) Inotropes and chronotropes
What is the common inotrope/chronotrope drug used for cardiac stress testing?
Dobutamine
A stress ECG test is contraindicated in what patients?
Those with baseline ECG abnormalities
What stress test modality is used to look for regional wall motion abnormalities (RWA) or LV dilation?
Stress Echocardiography (ECHO)
What stress test modality provides information on perfusion defects between rest and stress, cardiac viability, and LV systolic function?
Stress Myocardial Perfusion imaging (MPI)
Regional wall motion abnormalities seen on a stress ECHO can be further broken down into what categories?
1) Hypokinesis
2) Akinesis
3) Dyskinesis
