This morning, Dr. James Stone joined KVEO ValleyCentral to discuss the potential effects energy drinks can have on heart health.

With growing concerns around highly caffeinated beverages, conversations like these are more important than ever. While energy drinks are widely available, they may carry risks, especially for individuals with underlying heart conditions or when consumed in excess.

The interview will be airing this afternoon on KVEO-TV (NBC 23) and KGBT-TV (CBS 4 News), so be sure to tune in.

At South Heart Clinic, we believe education is one of the most powerful tools in protecting your health. We’re proud to support opportunities that help inform our community on how to better care for their hearts and make mindful choices every day. ❤️

We’re excited to share a special Heart Month feature created by Harlingen Consolidated Independent School District highlighting Dr. Balderas and the importance of heart health through diet and exercise. 🥑🚴

In this video, Dr. Balderas breaks down how simple lifestyle choices, like staying active, eating balanced meals, limiting processed foods, and building healthy habits early can significantly reduce the risk of heart disease later in life.

Prevention starts young, and small daily choices make a big difference over time. We’re proud to partner with our local schools to help educate and empower the next generation about cardiovascular health.

Dr. Micheal Balderas from Harlingen Medical shares some tips for a healthier heart.

Dr. Frank Mazzola delivered an informative Doc Talk in honor of Heart Month, focusing on Atrial Fibrillation (A-fib), one of the most common heart rhythm disorders.

A-fib occurs when the upper chambers of the heart beat irregularly and out of sync with the lower chambers. This can cause symptoms like:
-Heart palpitations
-Shortness of breath
-Fatigue
-Dizziness or lightheadedness

Dr. Mazzola discussed what causes A-fib including high blood pressure, heart disease, thyroid disorders, sleep apnea, and even stress and the importance of early diagnosis.
Education is prevention. The more our community understands A-fib, the better we can reduce complications like stroke and heart failure. ❤️

Dr. Frank Mazzola invites you to join him for our final Doc Talk of Heart Month today at 5:30pm!

Yesterday, Dr. Eduardo Flores had the privilege of speaking at Harlingen Medical Center in honor of Heart Month, sharing an important message: Lowering LDL cholesterol lowers cardiac events. ❤️

LDL is often called the “bad” cholesterol because elevated levels can lead to plaque buildup in the arteries. Over time, that buildup increases the risk of heart attacks. The good news? Lowering your LDL can significantly reduce that risk.

Here are heart-healthy ways to lower LDL cholesterol:
-Choose heart-smart foods
-Stay active
-Maintain a healthy weight
-Avoid smoking
-Take medications as prescribed
-Know your numbers

Prevention is powerful. By lowering LDL today, we help reduce heart attacks tomorrow, and potentially prevent the need for procedures down the road.

Your heart deserves better.
And we’re not just talking about your ex. 😉

All jokes aside, your heart works for you every second of every day. It deserves attention, prevention, and care. Take time to check your blood pressure, move your body and schedule an appointment with your cardiologist.
