World Pulmonary Hypertension Day, annually celebrated on the fifth of May, highlights the global impact of Pulmonary Hypertension (PH) - a lethal hemodynamic and pathophysiological disease, that affects a large number of children and adults worldwide. As a student intern at Child Heart Foundation, I’ve had the opportunity to explore the nuances of this chronic respiratory disease, by analysing medical research papers, case studies of patients, along with its poignant statistics (reduced life expectancy and appalling death rate).
Pulmonary Hypertension is described
as the abnormal increase in pressure of the arteries present in the lungs. The
most common kind of PH involves the pruning of the Pulmonary Artery, thus
disrupting the physiological process of blood circulation. While the muscular
walls of the Right Ventricle face immense pressure and weaken, the Left Auricle
and Ventricle of the heart receive paucity of blood, resulting in a myriad of
complications. Based on aetiology, the World Health Organisation has classified
PH into five distinctive groups - which has further stimulated case-based
research, as well as aided in customized patient care. However, the primary
cause of such a life-threatening disease remains unknown, and is daunting from
a psychosocial perspective.
In my perspective, one of the biggest
challenges in PH management is the lack of awareness - given the fact that
symptoms are generic, and are not specific to PH. This ultimately leads to delay
in diagnosis. In most developing countries, the disease is either
underdiagnosed or misdiagnosed. One should always be aware of alarming
symptoms, such as cyanosis (bluish tint on lips and skin), dyspnea (shortness
of breath) and syncope (fainting spells) and seek immediate medical help.
Furthermore, one should also be aware of risk factors that could instigate the
disease, such as smoking, the usage of illegal drugs and obesity.
The abovesaid, treatment is not
freely accessible in developing countries, and is prohibitively expensive (approximately
five lakhs), which along with lack of awareness, makes PH a fatal disease. Further,
not all major drug companies are interested in these developing markets, which
further accentuates the challenge of free accessibility of medication.
Action
follows Awareness - Local fundraising, International Charity Programmes, and
the involvement of authorities and governmental bodies seem plausible only when
enough awareness has been created in communities. In order to achieve the
aforementioned objective, it is indispensable to encourage the world in
bringing more advocacy/research and setting up infrastructure for the treatment
of PH. With the ongoing COVID 19 Pandemic, the significance of global health
cannot be better exemplified.
This World PH Day, I urge you to take
the first step - the onus of spreading awareness lies within you. Be a global
citizen. Educate yourself, your family/friends, and caregivers, and seek timely
medical aid on the onset of symptoms. This is the first stride towards a world
of healthier and disease-free lungs.
