62125Determination of the link between hypertension and Covid-19ClosedFeasibility StudiesInnovate UKHypertension (uncontrolled high blood pressure) is the leading preventable cause of premature death worldwide. Globally, 1.39bn people are estimated to have hypertension, and it caused ~10.7 million deaths in 2015\. It is projected to affect more than 1.5 billion people around the world by 2025\. In the UK ~30% of adults have hypertension, 9.5m have a diagnosis, and a further 5m people in England alone may have hypertension yet be unaware. In the current pandemic of COVID-19, people with hypertension are facing additional challenges in managing their condition as they are: \*socially isolating and not being able to meet with their GP/Healthcare Professional (HCP) with the same frequency \*reading stories in the press and scientific literature that indicate that a high percentage of patients with hypertension who contract COVID-19 have severe illness, are admitted to an intensive care unit, receive mechanical ventilation, or die. Being able to remotely monitor people with hypertension through use of a phone app that records daily BP readings, current treatment regimens and indicate any COVID-19 symptoms will address a current clinical need and enable medical management and patient engagement without the need for direct patient-HCP contact. We aim to update an already developed phone app designed for a hypertension focussed clinical study to include additional features for deployment in a new clinical trial in a COVID-19 setting. The trial will aim to demonstrate a "business as usual" approach to managing and monitoring a long term condition as well as collecting data help to answer questions that are of concern for the hypertension community namely: \*Does blood pressure drug use and/or level of blood pressure control affect risk of COVID-19 infection? \*Does blood pressure drug use and/or level of blood pressure control affect severity of COVID-19 illness/pneumonia? \*Do particular types of blood pressure medication affect risk of COVID-19 infection?
