Your Heart is in Your Hands


What’s the secret to a healthy heart? You, as it turns out.

“Doctors are here to help patients, but patients have to help themselves,” said Victor J. Castro, M.D., a board-certified interventional cardiologist who recently joined South Texas Health System Clinics in McAllen.

Castro is highly trained and skilled in identifying and treating a wide range of heart conditions, from acute coronary syndromes such as heart attacks to chronic issues such as congestive heart failure, blocked arteries, and more. He earned his medical degree from Universidad Peruana Cayetano Heredia in Lima, Peru, and completed his residency in internal medicine and fellowships in critical care, heart failure/heart transplant, and interventional cardiology at New York Medical College in Valhalla.

Whether providing care in his office, virtually or in the hospital, patients can expect to receive dedicated, compassionate attention.

“I enjoy taking care of patients, and seeing the happy faces of their family when they’re reunited after a serious condition is resolved,” he said.

He treats a wide spectrum of cardiac conditions, and like the entire cardiology team at South Texas Health System Clinics, has seen patients through dire emergencies. With access to advanced technologies, he and the specially trained team have been able to positively impact the quality of their patients’ lives.

Of course, Castro would prefer patients seek care before an issue becomes a medical emergency, when he and his colleagues can offer the most treatment options.

Cardiologists like Castro and the team specialize in diagnosing heart and vascular diseases, determining risk factors for heart conditions, and managing those conditions through medicine, surgery, and lifestyle modifications. The heart is a complex organ and the South Texas Health System Clinics’ heart team offers multiple programs to help ensure it is functioning at its best.

“Doctors are here to help, but the day-to-day care falls to the patient themselves,” Castro said.

You might not visit your cardiologist every day, but every day you have the opportunity to fix a healthy breakfast and take a brisk walk. Incorporating even thirty minutes of exercise into your routine can improve your overall health significantly.

“People can modify their lifestyles in many ways to take better care of themselves,” Castro said. “Most know this, but they sometimes need a little encouragement from their physician.”

To protect their heart health, Castro urges everyone to:

  • exercise regularly
  • trim extra weight
  • eat well
  • avoid smoking and excessive alcohol intake
  • take measures to reduce stress
  • make and maintain safely distanced social connections with others

Doctors will always be there to guide their patients, but it’s up to the patients to develop and follow healthy habits.

“I’m most looking forward to helping patients manage or overcome their heart issues so that they can get back to enjoying their lives with their loved ones,” he said.
