    I would like to acknowledge the quality of the content Amy Synnott has been producing.
    If we feel impatient, treading water, waiting for FDA clearance ... imagine how the team at CardieX are feeling !

    I particularly liked this post from 11/3/23. Plenty of references toi Conneqt Pulse and benefits of remote monitoring for Covid19 patients:

    How Cardiovascular Health Impacts Covid Outcomes

    On the third anniversary of the WHO’s declaration of global pandemic, we explore the relationship between high blood pressure and the risk of serious illness and death from Covid-19.

    By Amy Synnott

    If you suspected your blood pressure went up during the pandemic, you might not be wrong. Average blood pressure readings did, in fact, increase as the coronavirus spread, according to a 2022 observational study published in the journal, Circulation.1 And the resulting hypertension epidemic could have a huge impact on the number of strokes, heart failure, and heart attacks we see in the future, the researchers note. 2

    According to a 2020 study published in the European Respiratory Journal, hypertension is the most common comorbidity—the simultaneous presence of two or more diseases—seen among hospitalized patients with Covid 19. Of perhaps even greater concern: Those suffering from hypertension have a significantly higher risk of severe cases of Covid, resulting in hospitalization and even death.3

    Analyzing data from 1590 hospitalized patients from 575 hospitals in mainland China, researchers in this study found those who suffered from severe cases were 32.7% more likely to suffer from hypertension (versus 12.6% in non-severe cases). They were also more likely to have other conditions strongly associated with vascular dysfunction, including cardiovascular diseases (33.9% versus 15.3%), cerebrovascular diseases (50.0% versus 15.3%), diabetes (34.6% versus 14.3%), chronic obstructive pulmonary disease, aka COPD (62.5% versus 15.3%), and chronic kidney diseases (38.1% versus 15.7%). 4

    While hypertension accounted for a little over one third of the severe cases in this study, it’s worth noting that high blood pressure is closely linked to the development — and progression of —virtually all of those other comorbidities: cardiovascular disease, cerebrovascular disease (which affects blood flow in the brain), diabetes, COPD (a condition involving constriction of the airways and difficulty breathing), and chronic kidney disease, according to a report from the American Heart Association published in Circulation.5

    In a 2021 review in Frontiers of Physiology that explored the relationship between hypertension and Covid 19, researchers wrote, “It’s still unclear whether high blood pressure is a risk factor for acquiring COVID-19, or whether controlled blood pressure among patients with hypertension is or is not less of a risk factor.”6      

    How Hypertension Increase the Risk of Severe Covid Outcomes

    Cardiovascular health impacts Covid-19 outcomes in several ways, says Ray Townsend, M.D., the Director of Hypertension at the University of Pennsylvania School of Medicine. Individuals with high blood pressure have an increased risk of blood clots, and the coronavirus increases that risk. “Patients with Covid tend to form clots in the arterial circulation [the flow of blood in the vessels that supply the heart muscle], ” he says. “This can lead to stroke, heart attack, and peripheral vascular disease.”

    Townsend says venous clots — blockages in peripheral veins that supply blood flow to the legs and feet known as deep vein thrombosis — are also common in Covid patients. “This can cause a pulmonary embolism, where a blood clot travels to, and blocks, lung circulation.”

    A 2022 study published in the Journal of the American Medical Association found the risk of blood clots was higher among hospitalized Covid 19 patients than those hospitalized for influenza.7 Analyzing the outcomes of over 90,000 patients, the researchers at Perelman School of Medicine at the University of Pennsylvania found the risk of developing venous thromboembolism was 5.3% in patients diagnosed with the flu.

    Among those hospitalized for Covid, the risk of deep vein thrombosis was 9.5% before vaccine availability and 10.9 percent after COVID-19 vaccines became available. The risk of arterial thromboembolism, a blood clot that travels from one part of the body to the brain (stroke) or heart (heart attack), was 14.4 percent in patients hospitalized with the flu compared with 15.8 percent in those with Covid before vaccine availability and 16.3 percent during vaccine availability.

    “Although COVID-19 is primarily considered a respiratory illness, some evidence suggests the virus may also induce excessive blood clotting, or hypercoagulability, in the body,” the researchers wrote.

    Covid Increases Cardiovascular Complications

    Not only does hypertension increase risk of serious illness from Covid infection, the disease itself can negatively affect cardiovascular health for months after the acute phase has ended, according to a 2022 study published in the journal, Nature Medicine. 8

    Using medical databases from the US Department of Veterans Affairs, the researchers show that individuals who have recovered from COVID-19 are at increased risk cerebrovascular disorders, dysrhythmias (abnormal heart rhythms), heart disease, pericarditis (swelling or irritation of the membrane around the heart), myocarditis (inflammation — often caused by a viral infection — of the middle layer of heart wall), heart failure and thromboembolic disease (the aforementioned syndrome involving a blood clot that travels from one part of the body to another, blocking arteries and predisposing one to heart attack or stroke).

    These cardiovascular risks were seen even in those who avoided hospitalization (though they increased depending on their care setting during the acute phase, i.e., non-hospitalized, hospitalized and admitted to intensive care). “Our results provide evidence that the risk and one-year burden of cardiovascular disease in survivors of acute COVID-19 are substantial,” the researchers wrote.

    How to Reduce our Risk of Covid Complications from Hypertension

    The American Heart Association recommends that anyone with known or suspected hypertension should monitor their blood pressure (and BPV) with a home monitor. Taking blood pressure into your own hands can help you measure your progress in lowering your numbers, which can help reduce your risk of dying from Covid 19.

    The PULSE monitor is the first home device that’s FDA-approved to measure both central blood pressure and peripheral (brachial) blood pressure. Central blood pressure is important because it measures pressure coming out of the heart, which is different from pressure in your arm.

    Pressure at the heart is affected by factors like arterial stiffness (the rigidity of the arterial wall) so it provides a more comprehensive, nuanced picture of vascular health near key organs like the heart, brain, and kidneys.9

    The Cartesian Study

    In May 2020, the Artery Society in Europe announced the launch of a multicenter research project to explore the medium- and long-term consequences of COVID-19 on the cardiovascular system. The researchers are using technology to analyze central hemodynamic patient data. This is the same technology that will soon be available in the Conneqt Pulse, pending its imminent FDA approval.

    In the ongoing study, patients recently diagnosed with COVID-19 infection will be evaluated three to six months post diagnosis and again one year after diagnosis. Evaluation will include assessment of carotid-femoral PWV and central blood pressure waveform analysis as well as indicators of carotid geometry and stiffness, endothelial function, 24-hour central blood pressure, and small artery remodeling. Both a five- and 10-year clinical follow-up is planned to determine the risk of cardiovascular events associated with central hemodynamics and arterial stiffness among survivors of coronavirus.[5]

    The Importance of Remote Monitoring

    The vascular implications of COVID-19—and its ongoing presence in our lives—highlight the need for new and more sophisticated diagnostic techniques for remote monitoring of cardiovascular risk factors, including hypertension, arterial stiffness, and arterial inflammation. Combined with a traditional brachial cuff, the Pulse’s arterial waveform analysis offers both clinicians and researchers vital insights into their patients’ vascular health—including but not limited to arterial stiffness, pulse wave reflections, and central aortic blood pressure. As we continue to adjust to “the new normal with Covid,” this next generation technology represents a huge leap forward in the decentralization of critical health data.
