Can You Regenerate Your Heart after Heart Attack with Your Own Stem Cells?

Emory physicians are conducting research on how to use heart stem cells to help regenerate heart muscle in individuals who have experienced a heart attack. This effort is looking at ways stem cells can replace damaged heart cells and restore cardiac function.

Heart attack survivor Don Robinson was involved in a phase I clinical trial at Emory to test if his own stem cells would help regenerate his heart. For this, stem cells were taken from his body during a bone marrow transplant.

Clinicians involved in the trial are working to find cells that are likely to enhance blood vessel formation and protect the heart muscle from further damage. Mr. Robinson was given 10,000,000 cells after the heart attack, but before the scaring could take place. Scans performed as part of the study now show that Mr. Robinson’s heart has regenerated.

Emory is continually leading the way for advanced new treatments for heart disease. The phase I trial was testing safety of this procedure, but a phase II trial will soon begin at Emory to test this procedure further.

To learn more about Mr. Robinson’s experience, view the full story here.

Patient Story – Can Stress Lead to a Heart Attack?

Stress & Heart Attack RiskEmory patient, Donna Fielding, a healthy looking 41 year old mother of two is sure that stress and her high-intensity type A personality lead to her heart attack at 37. Her heart attack taught Donna to “take a step back, take a deep breath, and make a decision.” She doesn’t let the “little things” in life ruin her days any longer.

Emory physicians are doing research to study the connection between stress and heart attack risk. According Emory physician, Dr. David Sheps, when you get stressed your heart rate and blood pressure go up.

Heart Attack Atop Stone Mountain?

Atlanta Heart Walk 2011We hope having a heart attack on Stone Mountain is not something you will never have to worry about, but for one Emory Heart & Vascular Center patient, he had to take quick action to save his life. Luckily Howard Dean survived to tell the story and is now participating in the Emory HeartWise Heart Disease Risk Reduction program. He has even returned to hike Stone Mountain since that crazy day. View this Fox 5 Atlanta piece on Howard’s story:

Coronary Artery Calcium Scoring: What Does it Involve?

As we’ve mentioned in previous blog posts, atherosclerotic plaque is made up of a combination of fat, cholesterol, and calcium beneath the inner layer of the arteries. The coronary arteries supply oxygen-rich blood to the heart, and the presence and severity of calcified plaque in these vessels is an indirect way to assess the presence of atherosclerosis. The sudden rupture of one of these plaques can cause a heart attack, which is why it’s crucial to know if an individual has accumulated large amounts of atherosclerosis.

An easy way of accomplishing this is through a cardiac CT scan—with this non-invasive method we obtain information on the level of calcified plaque build-up. If calcified plaque is detected, atherosclerosis of the coronary arteries (coronary artery disease: CAD) is present. Two-thirds of heart attacks aren’t caused by the narrowing of the coronary artery, but as I mentioned—by plaque rupturing within the artery wall.

With CT scanning we calculate a calcium score, which measures the extent of plaque burden on your arteries. We report 3 pieces of information with the calcium score: 1) your own absolute score 2) your percentile of calcium score, which tells you how you rank in comparison with people of the your age, sex and race, and 3) your estimated “vascular age”; this is an estimation of how healthy (i.e. young) or diseased (i.e. older) your coronary arteries are compared to people with similar backgrounds, and therefore gives you an indication of your relative risk.

Other components of our Heart CT scan screenings include:

Blood Pressure

If your blood pressure measures over 140/90 mm Hg, it is considered to be at a high level. Some people refer to high blood pressure as “the silent killer” because it can cause severe damage on the body with little to no symptoms.  In fact, it can cause strokes, heart disease and damage to your kidneys or eyesight if left untreated.

Fasting Glucose

The fasting glucose test measures your blood sugar level for the presence of early diabetes. While diabetes is a treatable condition, it may not manifest for years, and can cause damage to your heart and vessels without you realizing it.

Framingham Risk Score

The Framingham Risk Score indicates your risk of experiencing a heart attack within ten years, and is based on a combination of factors such as your age, sex, your blood pressure and cholesterol level.

Overall Cardiovascular Risk

This measurement results from the combination of your Framingham Risk Score and calcium score.

Emory’s comprehensive cardiovascular screening is very reasonably priced at $150, and includes all of the components listed above.
