Bypass Surgery, Angioplasty or Medicines only ? Well , Let’s Call the Third Umpire !


Bypass Surgery,  Angioplasty or Medicines only ?
Well , Let’s Call the Third Umpire !

Many times, when I advise coronary angiography to a patient, one of the first questions posed by an anxious relative is: “After the angiogram will we have to be ready to undergo angioplasty immediately ?”

My usual answer is ‘NO’ if the patient is clinically stable and the disease not critical.

This answer is now vindicated by guidelines from various cardiology bodies as will be seen below. 

The field of cardiovascular medicine has seen great advances and at the same time burdened us with a wide variety of choices. On the one hand, the disease has become more and more complex with advanced age and associated conditions, with widely different expectations from patients (for example between a 91 year old and a 40 year old ) and widely different socio economic backgrounds, and on the other, an explosion of scientific information on newer and newer strategies of treatment.

Like the game of cricket, in some circumstances, the decision or choice is straightforward, for example, a patient with acute coronary syndrome (acute coronary problem-say, a heart attack) with an isolated single discrete narrowing of an artery, in whom angioplasty with stent implantation can be considered the treatment of choice with little or no disagreement, or a patient with significant angina, multiple coronary occlusions, and other severe complex disease in whom surgical revascularization is the treatment of choice.

Many patients, however, fit between these two extremes, and in this continuum, multiple considerations exist.

What method of treatment is best for such a patient ? A plethora of knowledge has accumulated about the relative merits of angioplasty versus surgical treatment versus “optimal medical therapy” alone, for such patients, and a potential danger exists of individual physician biases and ‘forcing’ one method of treatment.

That is the time, which is very often, that a third ‘umpire’ - A HEART TEAM is needed.

This multidisciplinary team, including an experienced cardiac surgeon, interventional cardiologist, and primary cardiologist/physician, working together with the present state of knowledge, as well as their individual experience can help to focus on specific patient considerations and fully inform the patient and family about the risks/benefits ratio of the various methods of treatment and help make choices.

By exploring the multiple options available and sharing them with patients and their families where applicable, more optimal shared decision making is achieved, along with a tailored recommendation for therapy for a more informed and engaged patient. The goal is that the patient and family be sufficiently educated about the alternatives available so that the best form of treatment can be selected rather than 'forcing' a method of treatment.

This team-based care –the ‘Heart Team Approach’ has now been strongly advocated by guidelines from various bodies such as  the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery as well as  American College of Cardiology and the American Heart Association.

Thus, whenever after a diagnostic angiogram, if the disease found is more complex than can be addressed easily in a straightforward manner or a potential exists for alternative methods of treatment such as angioplasty versus surgical treatment versus “optimal medical therapy” alone, the patient is taken off the table and the case discussed by the heart team followed by a discussion of the merits demerits of the various modalities of treatment with the patient and relatives.

 Of course, the above recommendation is mainly for stable patients whose condition may allow deferred decision making after the heart team meets and deliberates. For most acute, unstable or emergency patients the condition may not allow deferment of decision, which may have to be taken fast (within minutes) in the best interests of the patient. Thus in such patients ad-hoc angioplasty is the route usually recommended but rarely, emergency surgery.

Also, another point to remember is that both surgery and angioplasty do not exclude taking medicines. Modern cardiac medicines are the fundamental and integral part of all modalities of treatment, one of them being ONLY medicines.

While the age old adage ‘too many cooks spoil the broth’ does not apply here, ‘three heads are better than one’ applies very well – in Cricket and in Cardiology.
