Heart valve disease has been described as the next
cardiac epidemic. Due to an aging population it is increasing rapidly. It
currently affects one in eight people over the age of 75, but this number is
estimated to double by the year 2040 and triple by 2063.
As life expectancy increases, people make crucial
contributions to society and the economy for longer. Untreated valve disease
thus represents a barrier to active aging. On the other hand, early detection
and timely treatment result in increased longevity and quality of life.
Heart valve disease is caused by aging, disease, or
damage to one or more heart valves. Being linked to aging, it can also be
present from birth (congenital heart disease). It is a common condition, which
can be serious but is treatable. Any malfunction or abnormality of one or more
of the heart’s four valves, will affect the flow of blood through the heart.
Symptoms of heart valve disease can include tightness
or pain of the chest, shortness of breath, fatigue, irregular heartbeat,
fainting, and reduced physical activity. However, these are common symptoms in
people over the age of 65 and are often overlooked.
The heart has four heart valves that controls the flow
of blood in the heart. When the heart valves do not work properly, two types of
disease can develop: aortic stenosis (narrowing of the aortic valve) or mitral
regurgitation (degeneration of the mitral valve).
In the case of untreated, severe and symptomatic
aortic stenosis for example, the mortality rate varies between 25% and 50% per
year. These figures can easily be reversed through proper treatment, which
involves heart valve replacement, through conventional surgery or percutaneous
treatment.
The campaign by the European Society of Cardiology,
which took place last September, focused on educating the population on the
symptoms to look out for, which must not go unnoticed and, in this way, the
number of people treated in a timely manner will increase. Thus, more serious
outcomes, such as death, can be avoided. More than half the number of
symptomatic patients with severe aortic stenosis will die within two years of
developing symptoms if untreated.
However, some patients with valve heart disease develop no symptoms at all for many years or might never develop symptoms, even if the disease is severe, which can make diagnosis difficult. Regular medical evaluation, through auscultation of the heart with a stethoscope, is therefore crucial so that the patient can be immediately referred to a cardiologist, who will be able to carry out complementary tests to confirm the initial diagnosis.
