What are the signs of CAD that may be mistaken for other conditions?

Symptoms like indigestion or stomach upset, especially in women

What are the two main categories of labs to assess in cardiac diagnostics?

To assess the patient's risk and to assess if there's an active myocardial infarction (MI).

What does a cholesterol panel assess?

It assesses levels of LDL (bad cholesterol), HDL (good cholesterol), triglycerides, and total cholesterol.

What is the significance of elevated homocysteine levels?

Elevated homocysteine is a modifiable risk factor for coronary artery disease (CAD) and can cause damage to artery linings.

What role does inflammation play in vascular atherosclerosis?

Inflammation is a risk factor for CAD, with C-reactive protein (CRP) being a nonspecific marker for inflammation.

What cardiac enzyme is highly sensitive to cardiac injury?

Troponin I and T are highly sensitive and can be detected in blood serum within four hours of injury.

How long can troponin remain elevated after a myocardial injury?

Troponin can remain elevated for days after the injury.

What is the significance of creatine kinase (CK-MB) in cardiac diagnostics?

CK-MB is specific to heart muscle and can help diagnose both cardiac and non-cardiac disorders.

When does myoglobin peak after cardiac injury?

Myoglobin peaks within 4 to 12 hours after injury.

What is the gold standard for evaluating coronary artery disease?

Cardiac catheterization is the gold standard for evaluating CAD and can also be used for intervention.

What does a trans thoracic echocardiogram assess?

It assesses the valves of the heart and provides an ejection fraction measurement.

What is a normal ejection fraction range?

A normal ejection fraction is between 50% to 75%.

What is the difference between a trans thoracic echocardiogram and a trans esophageal echocardiogram?

Trans thoracic is non-invasive and uses ultrasound on the chest, while trans esophageal is invasive and uses a camera down the throat.

What are the two types of stress tests used in cardiac diagnostics?

Chemical stress tests and exercise stress tests (e.g., treadmill).

What EKG changes suggest coronary artery occlusion?

ST segment elevation, ST depression, and T wave inversion.

What is the significance of ST segment elevation in EKG?

It is a key indicator for diagnosing ST elevation myocardial infarction (STEMI).

What is the purpose of cardiac catheterization?

To visualize blockages in the coronary arteries and potentially perform interventions like angioplasty or stenting.

What is the role of triglycerides in coronary artery disease?

Elevated triglycerides can increase the risk for atherosclerosis and CAD.

How is CRP related to cardiac risk?

Elevated CRP levels indicate inflammation, which is a risk factor for coronary artery disease.

What is the peak time for CK-MB after a myocardial injury?

CK-MB peaks at 24 hours after injury.

What is the significance of myoglobin in diagnosing reinfection?

Myoglobin spikes quickly after injury and returns to normal quickly, making it useful for detecting reinfection.

What is a key nursing intervention for patients with increased chest pain during exercise?

Obtaining a clear history of the patient's condition.

What lifestyle factors should be assessed in patients at risk for coronary artery disease (CAD)?

Family history, smoking, alcohol consumption, exercise, diet, and occupation.

How does occupation relate to cardiovascular risk?

Certain occupations may increase stress or exposure to environmental factors that heighten CAD risk.

What is the significance of diabetes in relation to CAD?

Diabetes is a risk factor for CAD and may present atypically.

What should a head-to-toe assessment for a cardiac patient include?

Assessment of pain, its radiation, heart rate and rhythm, murmurs, and vital signs.

What is cardiac rehabilitation?

An individualized program to improve patient outcomes post-cardiac event, including physical activity and lifestyle education.

Who can benefit from cardiac rehabilitation?

Patients after cardiac surgery, MRI, or those recently diagnosed with heart failure.

What dietary recommendations are important for cardiac patients?

Increase fruits, vegetables, whole grains, fish, poultry, beans, nuts; limit saturated fats, fatty meats, sugary foods, and sodium.

What is the approach to physical activity for sedentary patients post-cardiac event?

Start low and go slow to allow the heart to adjust to increased activity.

Why is maintaining a healthy weight important for cardiovascular health?

Abdominal obesity puts extra stress on the heart.

What role do social determinants of health play in cardiovascular health?

They affect a patient's ability to maintain a healthy lifestyle and make necessary changes post-cardiac event.

What does 'time is muscle' refer to in a cardiac context?

The longer the delay in treatment for ischemia, the greater the risk of long-term complications.

What are potential complications of anticoagulant medications?

Major complications include bleeding, such as gastrointestinal bleeds.

What complications can arise from cardiac catheterization?

Bleeding at the insertion site and complications from anticoagulants used during the procedure.

What are serious complications following coronary artery bypass graft (CABG) surgery?

Complications can include stroke, infection, graft failure, kidney failure, arrhythmias, and possible death.

How can timely intervention affect patient outcomes in cardiac care?

Quicker recognition and treatment can reduce complications and improve survival rates.
