WHAT IS PULMONARY HYPERTENSION?

Pulmonary hypertension is a complex disorder with multiple pathologies.  This is the syndrome resulting from restricted flow through the pulmonary arterial circulation causing high pulmonary arterial resistance which has significant negative impact on right heart (RV) and eventually right ventricle failure.ph_med_hr

This is a serious condition with poor prognosis.  There are several new therapeutic modalities available but still has 14-16% mortality within one year.  Physicians can assess who has poor prognosis. Among these indicators and most important are 1. Poor exercise capacity, 2. Poor RV function by echocardiography, 3. High BNP in blood, enzyme indicative of heart failure. Primary pulmonary hypertension is much more common in females.

Primary cause, although still not completely known, but it has some genetic roots.  It is manifested as autosomal dominant disorder but incomplete penetration, i.e. can skip one or two generations. However, it is commonly associated with liver dysfunctions, connective tissue disorders (scleroderma, lupus, rheumatoid arthritis, etc.), HIV, drugs & toxins.  Patients who have a history of blood clots in the lungs can also develop pulmonary hypertension.  People who have COPD are also prone to this disorder.

Diagnosis heavily relies on a good history and physical exam.  Then EKG and echocardiogram with pulmonary function tests are essential for initial screening.  Confirmation is done by right heart catheterization.  Again, we must rule out other causes like COPD, left heart failure, HIV and connective tissue disorders.  At Cardiac Center, we can perform all these screening tests and we have pulmonary Hypertension specialists who are board certified interventional cardiologists, to perform right heart cath to confirm diagnosis.  These kinds of testing should only be done by qualified vascular specialists.

In early stages, patients may not have any symptoms.  The most common symptom is shortness of breath.  Patients also feel more tired and fatigued.  They may have chest pain with or without activity.  They also feel dizziness and a feeling of passing out.  Palpitations are also common in these patients.  When disease is advanced, they start having swelling of legs and then fluid accumulation in upper parts of the body.

Management requires multi-disciplinary collaboration.  Basic treatment includes oxygen therapy, careful diet, and tailored exercise.  All patients should be on blood-thinners like Coumadin.  Those patients should have a very tight preventative schedule for vaccinations and avoid pregnancy at all costs.  Diuretics are the first line of therapy to reduce fluid retention.  Some patients also benefit from calcium channel blockers.

Specific therapies are emerging and include so for these class of drugs to tackle this condition.

  1. Prostaglandis, which is usually given by IV and its main therapy for critically ill patients.  First drug showed mortality benefits was epoprosterol give continuous IV infusion.  This is followed by Treprostinil – can give s.c., Iloprost – aerosol rx 6 times per day
  2. Endothelial receptor antagonist
  3. Phosphodiesterase inhibitors

The last two are given in mild to moderate conditions.  We can combine the above medications to maximize benefits.  These patients need to be followed closely by pulmonary hypertension specialist in properly designated centers for pulmonary hypertension prescriptions.  They need to be seen for 3-6 month follow ups.

Cardiac Center of Texas to Offer Free Screenings for Peripheral Artery Disease

PAD SCREENING SAVES LEGS & LIVES

 

Cardiac Center of Texas will offer free screenings for peripheral artery disease, or PAD, for high-risk patients.

 

The screenings, which involve taking a person’s blood pressure in the legs and ankles, are painless and take about 10 minutes. They are available from 8 a.m. until 5:00 p.m. on Mondays and Wednesdays at Cardiac Center of Texas; registration is required. Call 972.529.6939.

 

Most often found in the legs, PAD is caused by the buildup of plaque (atherosclerosis).  It can cause pain, disability, organ failure and other serious consequences to lifestyle and health – even death.  Atherosclerosis in the peripheral arteries is often accompanied by the same problem in the coronary arteries, which is heart disease. Also, it is strongly associated with blockages in the carotid arteries in the neck which eventually could lead to stroke. Ten million US citizens over age 40 have PAD; the majority of them are asymptomatic.  That is why high-risk patients benefit from this screening.

 

Anyone experiencing leg cramping or pain with walking or leg pain at rest should get screened. Slow-healing wounds or sores on legs or feet also call for a screening. Those at-risk include those over 50 with diabetes, those who are obese or those who have a family history of heart disease. High blood pressure, high cholesterol, smoking, other circulatory problems, and a family history of PAD also put patients at advanced risk. Those who are African-American and Native-American also are at a higher risk.

 

FREE SCREENING AVAILABLE TO HIGH-RISK PATIENTS

 

PAD on its own threatens vital organs, risks loss of limb and life and affects productivity, lifestyle, and quality of life.  Also, PAD is associated with a much higher risk of heart disease.  So, it’s important to get screened if you have these risk factors:

 

  • Cold, painful, tingling or burning legs
  • Leg pain that subsides with rest, claudication
  • Loss of sensation in the legs
  • Poor wound healing
  • Over age 65
  • Established heart disease (i.e. heart attack, angioplasty, or bypass)
  • Over age 50 with Type I or Type II Diabetes
  • Over age 50 and a current smoker

North Dallas Research Associates and Cardiac Center of Texas Begin Enrollment in TOBA II BTK Clinical Trial for New Peripheral Revascularization Treatment Option

Dr. Khan Deployed the First Below the Knee Tack System in the South East Region and Only Second in the Country      

 

MCKINNEY, Texas, March 2, 2017 /PRNewswire/ – North Dallas Research Associates and its private practice, Cardiac Center of Texas, announced today their participation in the Tack Optimized Balloon Angioplasty II Below the Knee (TOBA II BTK) clinical trial. TOBA II BTK is a study that offers physicians a new option to treat patients suffering from advanced peripheral artery disease (PAD) or critical limb ischemia (CLI). Using the Tack Endovascular System®, the innovative technology is designed specifically to repair dissections following standard balloon angioplasty in the popliteal and tibial arteries with minimal stress to the vessels.

 

“We’re very excited to enroll the first patient in Texas to be treated in this groundbreaking clinical study,” said Dr. M. Akram Khan, Cardiologist at Cardiac Center of Texas. “TOBA II BTK provides the latest vascular technology for those in the Dallas area suffering from advanced PAD.”


PAD is a disease of the blood vessels in the legs and feet that occurs when arteries become narrow or clogged and don’t receive enough blood flow to meet the body’s needs. A recent analysis suggests more than 8 million Americans have peripheral artery disease, with 12-20% of individuals ages 65+ being affected. When left untreated, PAD can lead to critical limb ischemia (CLI), a more serious form of the disease. There are more than one million people in the United States living with CLI. CLI patients experience similar symptoms to PAD patients; however, CLI symptoms can significantly increase in severity from pain when resting, to open sores, to life-threatening conditions like gangrene, and can eventually require limb amputation in some patients. According to the U.S. Department of Health and Human Services, clogged arteries in the legs, just like clogged arteries in the heart, put individuals at risk for heart attack or stroke.

The Tack Endovascular System is equipped with self-sizing technology that allows one Tack implant to fit arteries ranging from 1.5mm to 4.5mm in diameter. This flexibility eliminates the need to precisely size the device to the arterial diameter, which is necessary with conventional stents. The device then allows physicians to “spot treat” the vessel only where dissections are present, rather than leave dissections untreated or covering them with large metal stents. This technique minimizes the amount of implanted metal and reduces vessel trauma and inflammation.

“Advanced PAD and CLI are large areas of fast-growing unmet need, both clinically and from a health economics perspective,” added Dr. Khan. “Patients with CLI suffer from debilitating symptoms and have few effective treatment options. It is important for the medical community to collaborate in this study to further the treatment options for patients with such advanced disease.”

Additional information regarding this trial can be found at clinicaltrials.gov by searching the term NCT02522884.

BIOTRONIK Launches CardioMessenger Smart Portable Remote Monitor For Implanted Device Patients

Cardiac Center of Texas first in North Texas to implant Pacemaker with New Monitor

LAKE OSWEGO, Oregon, May 24, 2016 — BIOTRONIK, a global leader in cardio- and endovascular medical technology, today announced the launch of CardioMessenger Smart in the United States. CardioMessenger Smart is a portable monitoring device, about the size of a modern smartphone, that keeps pacemaker, implantable cardioverter defibrillator (ICD), and insertable cardiac monitor (ICM) patients connected to their physician remotely, enabling more efficient care management‑-anywhere in the world. Dr. Akram Khan has implanted the first one of these pacemakers with the CardioMessenger Smart in North Texas.

“The clinical and economic benefits of remote monitoring have been well established over a decade of clinical studies,” stated Dr. Akram Khan of Cardiac Center of Texas. “But these benefits are only realized if patients consistently use the technology. When we make the remote monitoring process easy for patients, we increase the likelihood of patient adherence, which has been demonstrated to improve health outcomes.”

The portability of CardioMessenger Smart helps ensure patient compliance and the consistent transmission of data necessary for physicians to identify and prevent potential cardiac events. CardioMessenger Smart is fully automatic, providing data daily and at the time of an abnormal cardiac event via cellular network to physicians without any involvement or requirement from the patient.

 

Cardiac Center of Texas Opens Second Location

Cardiac Center of Texas recently announced plans to open its second office location in Plano, Texas in June of 2016. The new office will be approximately fifteen miles from its current location in McKinney, TX.

For Cardiac Center of Texas, a full service cardiology clinic, the additional office space means improved patient service, ability to accommodate patients in the Plano area, and room for growth.

Cardiac Center of Texas will now occupy Suite 209 in the Doctors 1 Building on the Medical Center of Plano campus.  “The additional office space will provide greater efficiency in how we serve patients. As we started to outgrow our current office and now that we have welcomed an additional interventional cardiologist, Venkata Chilakapati, MD, to the team, space and efficiency have been affected. We are now able to open more appointment times and improve patient flow and wait times. We expect this to improve convenience for the patients who prefer Plano, and most importantly our availability for more appointment opportunities,” said Practice Manager, Alicia Hicks.

“We were fortunate to find such a nice space so close to our current office. We really wanted to limit the impact that opening an additional office could have on our patients and our employees. I don’t think we could have found a better location for our team. Our new location and enhanced operational efficiencies will help us continue to grow and evolve to keep pace with our patients’ needs, allowing us to provide exceptional care along the way,” said Dr. M. Akram Khan, President and CEO.

Construction of the new space is slated to be complete near the beginning of June. If plans remain on schedule, Cardiac Center of Texas will move in early to mid-June, at which time the address for the second location will be:

1600 Coit Road, Suite 209
Plano, TX 75075

All of Cardiac Center of Texas’s phone numbers and fax numbers will remain the same.
