Angina pectoris, which is an oppressive pain, may indicate the presence of microvascular disease of the small arteries, a more frequent condition in postmenopausal women and in people with diabetes, hypertension or a history of cardiomyopathy.
"The most well-known coronary disease is that caused by atherosclerosis, where some coronary artery is partially or totally obstructed. However, there are diseases that still share the same characteristic symptoms, have another origin, are outside the great arteries and are located in the smaller ones, whose functioning is not evaluated with the usual studies, "explained Dr. Ricardo Iglesias. ), former President of the Argentine Society of Cardiology.
Those who disorders in the microcirculation, often hospitalized because they persistently experience chest pain but receive a battery of conventional it seems they have nothing. Today we know that the prognosis for this disease is not so good, because many patients in whom this condition evolves may end heart attack, even in heart failure or death.
"You have to have a new vision, another opening to see that coronary disease exists beyond the atherosclerotic plaque, sometimes even coexist, "said the expert recently during a presentation on the subject, called"Cardiovascular disease, in addition to atherosclerotic plaque", Churches argues.
The specialist gave the example of patients who have a blocked artery, through which they undergo a technique known ascatheterization, Which clears the artery and removes the atherosclerotic plaque: & # 39; The data indicate that, among them, 1 in 3 will still have pain within 6 months, even if this intervention has been successful and the artery is well. There is, of course, atherosclerotic disease with microcirculation problems"
It needs to be considered, he added, that there may be another mechanism involved "that is often not detected through a catheterization and other diagnostic methods should be used, such as nuclear magnetic resonance or positron emission tomography (PET). ), which are somewhat more sophisticated studies that evaluate how minor arteries contract or dilate; this is a concept innovative"Concluded the specialist.
