“Important cardiovascular decisions deserve time, continuity, and careful clinical reasoning.”
Patients may arrive with concerning symptoms, an abnormal test, conflicting recommendations, or a diagnosis they want to understand.
Dr. Patel’s goal is to review the complete picture and available evidence, explain what is known and uncertain, and recommend the next step most likely to help.
The plan may involve testing, a procedure, medication, prevention, observation, or reassurance. Patients should understand the reasoning behind it.
-
A Complete Review
Your symptoms, history, medications, records, test results, images, and goals are considered together.
-
A Clear Explanation
Understand the findings, what they mean, what remains uncertain, and your treatment options.
-
Testing With a Purpose
Testing is recommended when it can clarify a diagnosis, guide treatment, or improve the assessment of cardiovascular risk.
-
Continuity of Care
Dr. Patel remains closely involved in your evaluation, treatment, procedures he personally performs when appropriate, and follow-up.
-
Communication With Your Clinicians
For referred patients, Flow works to share findings, recommendations, and the follow-up plan with the referring clinician.
Areas of Focus
Thoughtful evaluation and treatment across coronary, vascular, rhythm, heart-failure, and complex cardiovascular concerns.
Coronary Heart Disease
Evaluation and treatment of chest discomfort, abnormal stress testing, coronary artery disease, previous coronary stents, complex coronary disease, and questions regarding angioplasty, stenting, or bypass surgery.
Explore Coronary CarePeripheral Arterial and Venous Disease
Evaluation of leg pain with walking, circulation problems, non-healing wounds, peripheral artery disease, deep vein thrombosis, venous obstruction, leg swelling, and venous insufficiency.
Explore Vascular CareHeart Rhythm Symptoms
Evaluation of palpitations, atrial fibrillation, unexplained rapid or slow heart rates, dizziness, fainting, and suspected heart-rhythm disorders.
Explore Rhythm EvaluationHeart Failure and Cardiovascular Prevention
Evaluation of shortness of breath, edema, cardiomyopathy, heart failure, valve disease, hypertension, cholesterol disorders, and overall cardiovascular risk.
Explore Heart Failure and PreventionA Clearer Second Opinion
A second opinion can help you understand a proposed procedure, conflicting recommendations, symptoms that persist after treatment, or questions about your test results and options.
When possible, patients should provide their previous records, angiogram or imaging reports, medication list, and relevant test results before the appointment.
