Heart disease deaths rose during the COVID-19 surge mainly because the pandemic disrupted routine medical care, delayed emergency treatment, and made people more likely to avoid hospitals even when they needed urgent help. In many cases, the virus itself also increased the risk of heart complications. Together, these factors created a dangerous combination that led to more fatal heart events. For related context on how the pandemic affected cardiovascular care, see Coronary heart disease deaths: Why Haven’t Declined.
The pattern was not caused by one single issue. Instead, heart disease deaths increased because care was interrupted at several points at once: people hesitated to seek help, clinics reduced normal visits, hospitals were stretched thin, and COVID-19 made some underlying conditions worse. The result was that more people reached a crisis stage before receiving treatment.

Why heart disease deaths increased during the COVID-19 surge
The biggest reason heart disease deaths rose was not just heart disease itself, but the way the pandemic changed how people accessed care. During COVID-19 surges, hospitals were overwhelmed, clinics reduced in-person visits, and many people feared getting infected if they sought treatment. As a result, symptoms that normally would have led to immediate medical attention were often ignored or delayed.
This mattered because heart disease is time-sensitive. Conditions such as heart attacks, severe arrhythmias, heart failure flare-ups, and strokes can become deadly quickly without prompt treatment. When people waited too long to call for help or get to the emergency room, the chances of survival dropped.
The rise in heart disease deaths also reflected a broader pattern seen throughout the pandemic: people were less likely to receive timely, preventive, or follow-up care. That meant problems that could have been managed earlier were more likely to become emergencies.
In public health reporting, this kind of increase is important because it shows that a crisis can affect more than the disease it is named after. The COVID-19 pandemic changed behavior, hospital flow, and treatment timing, and those changes affected heart disease deaths in ways that were not always visible at first.
How delayed care contributed to more deaths
One of the clearest reasons for increased heart disease deaths was delayed treatment. Many people experienced chest pain, shortness of breath, palpitations, or other warning signs but chose to stay home. Some assumed their symptoms were related to anxiety, fatigue, or COVID-19 rather than a cardiac emergency.
Delays happened for several reasons:
- Fear of catching COVID-19 in hospitals
- Concern about overburdening the healthcare system
- Confusion about whether symptoms were serious enough
- Difficulty getting appointments or transportation
- Reduced access to primary care and specialist visits
For heart disease, even a short delay can be dangerous. A blocked artery during a heart attack, for example, needs immediate treatment to restore blood flow. The longer the delay, the more heart muscle is damaged, and the greater the risk of death.
During the COVID-19 surge, this problem became even more serious because many patients tried to “wait it out” instead of calling emergency services. That choice sometimes turned a treatable event into a fatal one. In that sense, heart disease deaths became a warning sign of how dangerous delayed care can be during any public health emergency.
Some families also delayed care because they did not want a loved one to be exposed in a waiting room or ambulance. That concern was understandable, but it sometimes led to worse outcomes. The safest choice for true emergency symptoms was still to seek urgent treatment quickly.
Why fewer hospital visits led to worse outcomes
During the surge, emergency departments saw fewer patients for heart-related symptoms at first, but that did not mean fewer heart attacks happened. It often meant people were staying away until their condition became much worse.
Hospitals also had to change how they operated. Staff shortages, crowded intensive care units, and limited resources made it harder to provide fast care. In some areas, ambulance response times increased, and hospitals had longer wait times for critical procedures. These system-level pressures made emergency cardiac treatment less efficient than usual.
People with chronic heart disease were also affected. Routine checkups, medication reviews, and monitoring appointments were postponed. That meant blood pressure, cholesterol, diabetes, and heart failure were less likely to be controlled properly, increasing the chance of serious complications.
When care is interrupted for weeks or months, heart disease can worsen quietly. A patient may feel only slightly worse at first, but the condition can become unstable without regular monitoring and treatment adjustments. Heart disease deaths often rise after those small gaps add up.
That disruption also affected preventive care. A patient who would normally have had a medication change, a blood pressure check, or a test for worsening symptoms may have missed that chance. Over time, those small misses can create a much bigger risk of hospitalization or sudden death.
Did COVID-19 itself affect the heart?
Yes. COVID-19 is not only a respiratory illness. It can also affect the cardiovascular system. The infection may increase inflammation, strain the heart, and raise the risk of blood clots. In some patients, COVID-19 caused myocarditis, arrhythmias, or worsening of existing heart conditions.
For a deeper look at the infection’s broader public-health impact, the CDC’s overview of COVID-19 information and guidance explains how the virus can affect multiple organ systems, not just the lungs.
Even after the acute infection, some people experienced lingering cardiovascular effects. For individuals who already had heart disease, catching COVID-19 could make an already high-risk situation even more dangerous.
This means heart disease deaths rose for two main reasons:
- People were less likely to get timely care.
- COVID-19 itself made some heart conditions worse.
When those two factors overlapped, the result was a higher chance of sudden deterioration and death. That overlap helps explain why the pandemic produced so many indirect cardiovascular harms.
Researchers and clinicians also noted that severe infections can place additional stress on the body by increasing heart rate, lowering oxygen levels, and triggering inflammation. For someone living with coronary artery disease or heart failure, that extra strain can be enough to shift a stable condition into an emergency.
Which heart conditions were most affected?
Several types of heart disease likely contributed to the increase in deaths during the pandemic surge:
- Heart attacks: Delays in emergency treatment made them more deadly.
- Heart failure: Missed follow-ups and medication issues led to worsening symptoms.
- Arrhythmias: Uncontrolled abnormal heart rhythms can cause sudden death.
- Stroke related to cardiovascular disease: Delayed response reduced chances of recovery.
- Cardiac complications from COVID-19: Inflammation and clotting increased risk.
In many cases, people had more than one health problem at the same time, such as diabetes, high blood pressure, obesity, or kidney disease. These conditions increased the risk of severe COVID-19 and also made heart disease harder to manage.
That overlap helps explain why the pandemic was so dangerous for high-risk patients. Even a manageable cardiac condition could become life-threatening if infection, delayed care, and chronic disease collided at once.
Older adults were especially vulnerable because they were more likely to have multiple chronic conditions and less reserve when illness struck. But younger adults with serious risk factors were not immune. Heart disease deaths increased across groups when warning signs were ignored or care was delayed.
Why the death rate rose even when overall hospital visits fell
A confusing part of the pandemic was that some hospitals reported fewer heart-related admissions, yet more deaths from heart disease. That happened because fewer admissions did not mean fewer emergencies. It often meant people never made it to the hospital in time or arrived too late to be saved.
This pattern suggests that the pandemic did not reduce heart disease. Instead, it changed where and when people died. Some deaths likely happened at home, while others occurred after delayed care in the hospital.
In other words, a lower admission rate was not a sign of better health. It was often a sign of missed care, slower response, and more severe illness by the time treatment began.
It also shows why hospital data alone can be misleading. If fewer people arrive for treatment but more people die outside the hospital, the overall burden may be worse even though admission numbers look lower. That is one reason heart disease deaths remained a key public-health concern during the COVID-19 surge.
In practical terms, the decrease in visits may have hidden the true scale of the problem. If someone had chest pain at home and never called 911, that event would not show up as a routine hospital visit, but it could still end in tragedy.
How stress and lifestyle changes may have played a role
The pandemic also increased stress, which can affect heart health. Job loss, isolation, grief, financial hardship, and uncertainty all added emotional strain. Chronic stress can raise blood pressure, worsen sleep, and contribute to unhealthy habits.
Many people also became less active during lockdowns and spent more time sitting. Diet quality may have worsened, alcohol use increased for some, and access to healthy routines became harder. These changes did not cause the sudden rise in heart disease deaths on their own, but they may have added to the overall burden.
Stress can also make existing symptoms feel easier to dismiss. A person who is tired, anxious, or overwhelmed may ignore warning signs until the condition has already become severe.
For patients and families, the lesson is that heart health during a crisis depends on both medical care and daily habits. Keeping up with movement, medications, sleep, and nutrition can help reduce risk when healthcare access is disrupted.
Stress management mattered too. Simple routines such as staying connected to family, taking medications consistently, and following a provider’s advice for home monitoring could make a meaningful difference. These steps do not replace emergency care, but they can help reduce the chance that heart disease worsens unnoticed.
What patients and families can learn from this
One of the most important lessons from rising heart disease deaths during the pandemic is that emergencies do not stop during a crisis. Even when hospitals are busy or people are worried about infection, life-threatening heart symptoms still need immediate attention.
Families should know the common warning signs that require urgent care:
- Chest pressure, squeezing, or pain
- Shortness of breath that is sudden or severe
- Pain that spreads to the arm, jaw, back, or shoulder
- Fainting or near-fainting
- Sudden weakness, numbness, or trouble speaking
- Fast, irregular, or pounding heartbeat with dizziness
When any of these symptoms appear, the safest response is to seek emergency care right away. Waiting at home can turn a treatable event into a fatal one.
This is especially true for people with known cardiovascular risk factors. A history of heart disease, high blood pressure, diabetes, smoking, or obesity makes it even more important not to delay care. During the COVID-19 surge, the people most likely to be harmed were often the same people who already had the highest baseline risk.
Families can also help by making a plan in advance. Knowing which hospital to call, keeping a medication list ready, and understanding when to use emergency services can reduce hesitation when symptoms start. Preparation can save valuable time.
Common questions about rising heart disease deaths during COVID-19
Was heart disease death directly caused by COVID-19?
Not always. Some deaths were caused by direct COVID-19 complications, while others were due to delayed treatment, reduced access to care, or worsening of existing heart disease. In many cases, multiple factors were involved.
Did people actually have fewer heart attacks during the pandemic?
No, not necessarily. The number of hospital-treated heart attacks appeared to drop in some places, but that likely reflected fewer people seeking care rather than fewer heart attacks happening. Some heart disease deaths likely occurred before patients ever reached a hospital.
Why were hospitals less accessible?
Hospitals were dealing with COVID-19 surges, staffing shortages, bed shortages, and infection-control measures. Some routine services were postponed or limited to preserve resources for critically ill patients.
Who was most at risk?
People with preexisting heart disease, older adults, and those with risk factors such as high blood pressure, diabetes, obesity, and smoking were at highest risk. People who had COVID-19 and heart disease at the same time faced even greater danger.
When should someone seek urgent help?
Anyone with chest pain, sudden shortness of breath, fainting, one-sided weakness, or severe palpitations should seek emergency care immediately. During the pandemic, those symptoms were no less urgent than before.
Can lifestyle changes alone explain the rise?
No. Lifestyle changes and stress may have contributed, but they do not fully explain the pattern. The largest drivers were delayed care, disrupted treatment, and COVID-19-related heart strain. Still, healthier routines can help lower risk over time.
What this means for future public health
The rise in heart disease deaths during the COVID-19 surge showed that pandemics can cause serious indirect health consequences, not just deaths from the virus itself. Protecting heart health during public health emergencies means making sure emergency care remains accessible, patients are encouraged to seek help quickly, and chronic disease management continues even when the healthcare system is under stress.
Public health messages also need to be clear: chest pain, severe shortness of breath, sudden weakness, fainting, and other cardiac warning signs should never be ignored, even during a pandemic.
Long-term planning should also include better continuity of care, stronger telehealth options, and public messaging that reassures patients that emergencies will still be treated right away. Reducing fear can save lives.
Healthcare systems can also improve by preparing backup pathways for cardiac care during large outbreaks. That includes keeping emergency departments prepared for heart attacks, maintaining clear ambulance routing, and making sure patients know they should not stay home with dangerous symptoms. These changes can help reduce future heart disease deaths if another crisis disrupts normal care.
Bottom line
Heart disease deaths rose during the COVID-19 surge because many people delayed or avoided urgent care, healthcare systems were stretched thin, and COVID-19 itself increased cardiovascular risk. The pandemic made an already serious health problem more dangerous by interrupting treatment, worsening existing conditions, and keeping people from getting help when every minute mattered.
The key lesson is simple: heart symptoms are always medical emergencies, and getting care quickly can save lives, even during a public health crisis. In fact, prompt treatment becomes even more important when the system is under strain and delays can be deadly.
If warning signs appear, the safest choice is still to act quickly. That message matters now and will matter in future emergencies as well, because timely treatment is one of the strongest defenses against preventable heart disease deaths.
