Name of the Condition

• Atherosclerotic Heart Disease of Native Coronary Artery with Other Forms of Angina Pectoris
• Also known as Coronary Artery Disease (CAD) with Unstable Angina or Variant Angina.

Summary

• Atherosclerotic Heart Disease affects the coronary arteries, reducing blood flow to the heart muscle, leading to angina pectoris, a condition characterized by chest pain due to reduced oxygen supply to the heart.

Causes

• Primarily caused by the buildup of plaque in the coronary arteries.
• Plaque consists of cholesterol, fatty deposits, cellular waste, and calcium.
• Contributing factors include high blood pressure, high cholesterol, smoking, and a sedentary lifestyle.

Risk Factors

• Age (risk increases for men over 45 and women over 55).
• Family history of heart disease.
• High blood pressure, diabetes, and high cholesterol.
• Lifestyle factors such as smoking, poor diet, and physical inactivity.

Symptoms

• Chest pain or discomfort, often described as pressure or squeezing.
• Pain may radiate to neck, jaw, shoulders, arms, or back.
• Shortness of breath, fatigue, dizziness, and sweating.

Diagnosis

• Physical examination and medical history review.
• Electrocardiogram (ECG) to detect heart electrical activity.
• Stress tests to monitor heart function during activity.
• Coronary angiography and imaging studies like CT scans to visualize blockages.

Treatment Options

• Medications such as nitrates, beta-blockers, and statins to manage symptoms and reduce risk factors.
• Lifestyle changes including diet and exercise to improve heart health.
• Surgical procedures like angioplasty or coronary artery bypass grafting (CABG) for severe cases.

Prognosis and Follow-Up

• Prognosis varies depending on the severity and how well the condition is managed.
• Regular follow-ups to monitor heart health and adjust treatment plans as necessary.
• Lifestyle modifications and adherence to treatment can significantly improve outcomes.

Complications

• Myocardial infarction (heart attack) due to complete blockage of coronary artery.
• Heart failure or arrhythmias.
• Increased risk of sudden cardiac death.

Lifestyle & Prevention

• Heart-healthy diet rich in fruits, vegetables, whole grains, and low in saturated fats.
• Regular physical activity tailored to individual health status.
• Smoking cessation and moderate alcohol consumption.
• Regular health screenings to monitor and control blood pressure, cholesterol, and diabetes.

When to Seek Professional Help

• Seek immediate medical attention if experiencing severe or persistent chest pain, shortness of breath, or signs of a heart attack.
• Regular check-ups for ongoing assessment and management of known heart disease.

Tips for Medical Coders

• Ensure correct documentation of both coronary artery disease and the specific type of angina for accurate coding.
• Confirm whether the angina is stable, unstable, or variant to select the correct ICD-10 code.
• Be aware of common coding errors, such as misclassifying the type of angina or overlooking documented risk factors that may affect code assignment.
