Frequently Asked Questions

Dr. Gangasani opened ACG Heart & Vascular in the first week of August 2026, after caring for patients in Gwinnett County since 2000. The office is at 310 Philip Blvd, Suite 102, Lawrenceville, GA 30046. Patients he has seen in the past two years were mailed a letter with the new address and phone number. You are always free to choose your cardiologist. To continue your care with him, call 678-841-8412 or book at acgheart.com, and we will help you transfer your records.

It depends on your insurance. Many PPO and traditional Medicare plans let you book directly, while most HMO plans need a referral from your primary care doctor. Call us and we will check your plan for you before your visit.

We accept most major insurance plans. Credentialing with Oscar and Medicaid is in progress. Please call our office for the full list or to check your specific plan. We also offer clear, upfront self-pay pricing for patients without insurance or with plans we do not take.

Yes, we are welcoming new patients, and most are seen within 24 to 48 hours on weekdays. You can book an appointment 24/7 at acgheart.com or by calling 678-841-8412. Our scheduling team also answers the phone Monday through Friday, 8 am to 5 pm.

See a cardiologist if you have chest pressure or tightness with activity, a racing or irregular heartbeat, shortness of breath, leg swelling, dizziness or fainting. It is also wise if you have high blood pressure, high cholesterol, diabetes, or a family history of early heart disease. If you have chest pain right now, or chest pain with sweating, nausea or shortness of breath, call 911. Do not wait for an appointment.

Preventive cardiology finds and treats heart risk before a heart attack or stroke happens. We look beyond routine labs at your blood pressure, cholesterol, blood sugar, family history, lifestyle and, when useful, tests like a coronary calcium score or Lp(a). It is a good fit for anyone over 40 with risk factors, anyone with a parent or sibling who had early heart disease, and people of South Asian descent.

Most testing is done right here in our office. Our studies often cost less than half of hospital-based pricing. We offer:

• EKG
• Echocardiogram (heart ultrasound)
• Exercise treadmill stress test
• Nuclear imaging stress test
• Lexiscan (medication) stress test, for patients who cannot exercise on a treadmill
• Carotid ultrasound
• Heart rhythm monitoring (Holter and mobile telemetry)

For a nuclear or Lexiscan stress test, avoid all caffeine for 24 hours, including coffee, tea, soda, chocolate and decaf. Have nothing by mouth for 4 hours before the test. Wear comfortable clothes and walking shoes. Ask us whether to hold any of your medications that morning. Every patient receives a preparation sheet with step-by-step instructions for their specific test. A nuclear stress test takes about 3 hours. An echo, treadmill stress test or carotid ultrasound takes less than an hour.

People of South Asian descent tend to develop heart disease earlier, often in their 40s, and sometimes at a normal body weight. Contributing factors include insulin resistance, lower HDL, higher triglycerides and a higher rate of elevated Lp(a). National cholesterol guidelines list South Asian ancestry as a risk-enhancing factor. Early screening and prevention make a real difference.
