Common risk factors for heart disease in women include:
Our specialists evaluate and manage cardiovascular heart conditions in women across their lifespan, including:
Since heart disease is the leading cause of death for women, we focus on heart care prevention. Your doctor will create a care plan that helps manage your risk factors. This may include lifestyle changes, medications, and lowering high blood pressure and high cholesterol.
Your care team provides blood pressure monitoring to help you better understand your heart health and reduce the risk of severe conditions like heart attack, stroke and kidney disease. Whether you're being screened for high blood pressure (hypertension) or managing an existing condition, regular monitoring can keep you healthy. Your heart specialist may recommend doctor visit checks, home blood pressure monitoring or 24-hour blood pressure monitoring.
A blood test is a lab analysis of things that may be found in your blood. You may have blood tests to keep track of how well you are managing a condition, such as diabetes or high cholesterol. You may also have them for routine checkups or when you are ill.
A simple lipid blood test can give your cardiologist important information about your cholesterol levels to personalize your care plan to prevent heart attack, stroke and other heart conditions. A cholesterol test, also called a lipid panel, measures the levels of different types of fats in your blood, including total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides.
This minimally invasive procedure helps our cardiologists accurately diagnose heart conditions by evaluating how well your heart and blood vessels are working. A catheter is gently inserted into a blood vessel through the wrist or groin and guided to your heart’s chambers. A contrast dye is injected through the catheter to help capture images of your heart. This procedure helps your care team measure blood flow, check for blockages in the coronary arteries, evaluate heart valve function and determine how well your heart is pumping.
Our cardiology team uses advanced diagnostic tools and expertise to accurately identify a wide range of cardiac issues, ensuring you receive the right care as early as possible.

Our electrophysiology (EP) team performs advanced EP studies to diagnose the source and type of arrhythmias accurately. Using specialized catheters and real-time mapping, we evaluate your heart's electrical activity to guide the best treatment plan for your heart condition.
This is also called a treadmill or exercise ECG. This test is done to monitor the heart while you walk on a treadmill or pedal a stationary bike. Your doctor also monitors your breathing and blood pressure. A stress test may be used to detect coronary artery disease, or to determine safe levels of exercise after a heart attack or heart surgery. This test can also be done using special medicines that stress the heart in a similar manner as exercise does. Sometimes a stress test will collect ECG information along with heart ultrasound pictures. This is called an exercise or stress echocardiogram (echo). It's more sensitive and specific than ECG stress testing alone.
Our preventive cardiology programs focus on identifying and managing risk factors before heart problems develop. We deliver personalized care plans that include heart-healthy lifestyle guidance, advanced screenings and support. Our goal is to help you stay ahead of heart disease.
If you have been diagnosed with heart disease, we are here to support you. Your doctor works with you to create a personalized care plan. Heart disease may be managed with lifestyle changes, medication or a heart procedure.
