When people with COVID-19 started getting strokes and heart attacks, scientists began researching the connection. They soon realized that the virus was attacking not just the respiratory system, but the vascular system as well.

There’s a good reason why: this novel coronavirus attaches itself to the human body via receptors called ACE-2. “Those ACE-2 receptors are quite prevalent in a lot of places in the body, especially the endothelium layer of the arteries and veins,” says Dr. Swartz. “The virus can get in there and inflame the blood vessels.”

MSK Library Guides: COVID Impacts: Cardiovascular
"While COVID-19 is considered a "respiratory virus", it manifests through the entire body. Cardiovascular complications have been well-documented in acute COVID-19 infection, and recent research is showing that it also causes significant cardiovascular manifestations in the post-acute phase of the disease."

Doctors Warn COVID-19 Could Be a Hidden Trigger for Heart Attacks Long After Recovery
COVID-19 isn't just a respiratory illness — it can silently attack the heart. New research reveals that the virus accelerates plaque buildup in arteries, increasing the risk of heart attacks and strokes long after recovery. A new study has found that COVID-19, caused by the SARS-CoV-2 virus, is l

Strokes, heart attacks, sudden deaths: Does America understand the long-term risks of catching COVID?
Strokes, heart attacks, sudden deaths: Does America understand the long-term risks of catching COVID?

"A 35-year-old acquaintance drops dead from a hemorrhagic stroke. A friend in her 40s, and another in his 70s, experience recurrent spells of extreme dizziness, their hearts pounding in their chests when they stand. A 21-year-old student with no prior medical history is admitted to the ICU with heart failure, while a 48-year-old avid tennis player, previously healthy, suddenly suffers a heart attack. A relative is diagnosed with pericarditis, an inflammation of the protective sac surrounding the heart.

I can’t confirm the exact etiology of all these cases. But every one of the people I mentioned had a history of COVID either days or months beforehand–and all of them experienced only mild cases of infection at the time.

Is it possible, despite everything we know, that we still underestimate COVID’s reach and danger? It is not normal for me to know so many people with severe conditions. Not normal at all."

Remodeling of intracellular architecture during SARS-CoV-2 infection of human endothelium
Remodeling of intracellular architecture during SARS-CoV-2 infection of human endothelium
SARS-CoV-2 causes vascular dysfunction by stiffening endothelial cells, even without fully replicating in them. This applies to multiple variants (Alpha, Beta, Delta). This stiffening (loss of elasticity) disrupts blood flow regulation, promotes inflammation, and increases clotting risk. The study highlights endothelial dysfunction as a direct viral effect, not just due to systemic inflammation or cytokines.

Long-term Risk of Heart Attack, Stroke and Death Doubles with History of COVID-19 Infection
Long-term Risk of Heart Attack, Stroke and Death Doubles with History of COVID-19 Infection
The study found that people with any type of COVID-19 infection were twice as likely to have a major cardiac event, such as heart attack, stroke or even death, for up to three years after diagnosis. Stanley Hazen, MD, PhD summarizes the findings of this Cleveland Clinic led trial and implications for practice and future research.

Not to be sneezed at: cardiovascular disease after COVID-19 infection
Not to be sneezed at: cardiovascular disease after COVID-19 infection
COVID-19 has changed our way of life since it was first identified in December of 2019. While our understanding of the manifestations and outcomes of the immediate acute illness has improved, we are still learning about the medium to long-term impact of this diagnosis on patients’ health. For some time, it has been suggested that COVID-19 may be associated with incident cardiovascular events such as venous thromboembolism, stroke and myocardial infarction.1 However, the absolute risk of these events and whether an excess risk is present are challenging to determine without a contemporary reference population. This is particularly problematic in the midst of a global pandemic. The UK Biobank is a large robust contemporary cohort of middle-aged volunteers who were prospectively recruited between 2006 and 2010.2 In this cohort, half a million participants aged between 40 and 69 years provided informed consent for detailed clinical assessment, with data linkage to routine data sources including primary care and death register data. Raisi-Estabragh and colleagues3 identified 20 505 participants from the UK Biobank study who had recorded COVID-19 infection status, defined based on disease coding in primary care or hospital episode statistics using a positive antibody test or a positive reverse transcriptase PCR based test. The authors included participants from the first two waves of the COVID-19 pandemic and were able to perform matched analysis in 17 871 participants. The authors used 1-to-2 propensity score matching to link to a reference population of 35 742 patients without evidence of COVID-19 infection using nearest neighbour matching and tying with the date of COVID-19 infection. Several relevant variables were included for matching including age, sex, deprivation, body mass index, ethnicity, diabetes mellitus, …

COVID-19 Surges Linked to Spike in Heart Attacks
CDC data of 1,522,699 deaths from heart attacks in 10 years found that by the second year of the pandemic, rates of heart attack death had increased by 29.9% for adults ages 25-44, by 19.6% for adults ages 45-64, and by 13.7% for adults age 65 and older.
