Pneumonia and stroke are closely linked. Pneumonia can increase the risk of having a stroke, with bacterial pneumonia posing a 60% greater risk of a stroke than viral pneumonia. In addition, a stroke can also cause pneumonia. This is due to the paralysis or motor deficiency that can result from a stroke, which can cause dysphagia, or difficulty swallowing, leading to aspiration pneumonia.

Pneumonia can increase the risk of a stroke
Research published in the European Respiratory Journal found that several different organisms that cause respiratory infections, including S. pneumoniae bacteria, also increase the risk of heart attacks and strokes. The study, funded by the Academy of Medical Sciences, was the largest of its kind and found that respiratory infections can cause inflammation, leading to the development of blood clots and increasing the risk of a stroke.
The risk of a stroke is particularly high for older adults who have had pneumonia. A 2015 study found that seniors who develop pneumonia severe enough to require hospitalisation are at a higher risk of having a stroke for years after the infection. The risk is highest in the first year following infection but remains elevated for at least a decade, which was the maximum time period the researchers followed the patients. In the first 30 days, the risk is four times greater than that of people of similar ages who had not been hospitalised with pneumonia.
Pneumonia is also one of the most common medical complications following a stroke, with up to one-third of stroke patients suffering from it. This is often due to aspiration, with ill and neurologically impaired hospitalised patients at a high risk of aspirating and developing pneumonia.

Pneumonia can cause dysphagia, leading to stroke-related pneumonia
Pneumonia can cause dysphagia, which can lead to stroke-related pneumonia. Dysphagia is a common complication after a stroke, affecting approximately 30-65% of patients. It is characterised by difficulties in the passage of food or liquid from the mouth through the pharynx, oesophagus, and stomach. This can cause food or liquid to enter the trachea, known as aspiration, which can lead to pneumonia.
Pneumonia and flu infections can increase the risk of having a stroke by causing inflammation, which can lead to the development of blood clots. In addition, these infections can have harmful effects on the heart muscle. The risk of having a stroke is increased for up to one month after a pneumonia or flu infection.
Dysphagia can cause aspiration, which is when food, liquid, or other material enters the lungs or airway accidentally. Aspiration can cause serious health problems such as pneumonia, which is an infection of the lungs that can be life-threatening.
Oropharyngeal dysphagia is a risk factor for community-acquired pneumonia in the elderly. It is associated with a delay in the closure of the laryngeal vestibule, which is the flap of tissue that blocks food and drink from entering the trachea. This delay can cause food or liquid to enter the trachea, leading to aspiration pneumonia.
The early diagnosis and treatment of dysphagia in stroke patients are important to prevent stroke-associated pneumonia. All stroke patients with clinical signs of dysphagia should be thoroughly assessed and provided with appropriate treatment options if necessary.

The risk of stroke is highest in the first year after a pneumonia infection
It has been found that pneumonia can increase the risk of having a stroke, with the risk being highest in the first year following the infection. This risk is especially high for seniors who have had pneumonia severe enough to require hospitalization. For adults 65 and older, the risk of a stroke is highest in the first year following the infection but remains elevated for at least a decade—the maximum time period that was studied. In the first 30 days, the risk is four times greater than that of people of similar ages who had not been hospitalized with pneumonia.
Research has shown that several organisms that cause respiratory infections, including S. pneumoniae bacteria, also increase the risk of heart attack and stroke. These infections cause inflammation, which can lead to the development of blood clots. The influenza virus and S. pneumoniae, the most common pneumonia-causing bacteria, can also have harmful effects on the heart muscle.
The link between pneumonia and an increased risk of stroke was confirmed by Dr. Vicente Corrales-Medina of the Ottawa Hospital, who said that doctors have been observing this connection for years. He added that there had been no rigorous research conducted previously to determine whether this link was a coincidence or a genuine association.
Experts recommend that patients and doctors take steps to reduce the risk of contracting pneumonia, such as getting vaccinated. It is also important to control other factors that can lead to cardiovascular disease, such as blood pressure and cholesterol levels. While the exact reason for the link between pneumonia and an increased risk of stroke is unknown, it is believed that other infections may also have a similar effect.

Bacterial pneumonia is associated with a higher risk of stroke than viral pneumonia
Pneumonia is an infection in the lungs caused by bacteria, viruses, or fungi. Bacterial pneumonia is usually more severe and common than viral pneumonia, often requiring a hospital stay and antibiotic treatment. Viral pneumonia, on the other hand, often resolves on its own and may not necessitate specific treatment.
Research has found that pneumonia increases the risk of having a heart attack or stroke. People who have had pneumonia may be up to six times more likely to suffer from a heart attack or stroke in the days and weeks following the infection. The risk is particularly elevated in the first two weeks following the infection, with the risk of stroke remaining high for up to a month.
A study by the Intermountain Heart Institute at Intermountain Medical Center found that bacterial pneumonia posed a significantly greater risk to the heart than viral pneumonia. The study evaluated nearly 5,000 patients diagnosed with pneumonia and found that those with bacterial pneumonia had a 60% greater risk of a heart attack, stroke, or death than those with viral pneumonia. This finding underscores the importance of aggressive treatment and careful monitoring of patients with bacterial pneumonia to reduce their risk of adverse cardiac events.
The increased risk of cardiovascular events associated with pneumonia is believed to be linked to the inflammatory response triggered by infections. Inflammation can lead to the development of blood clots, which can block blood flow to the heart or brain, resulting in a heart attack or stroke. Additionally, the inflammation caused by bacterial pneumonia can destabilize plaque buildup in the arteries, leading to a blockage that can cause a heart attack or stroke.
The findings of these studies highlight the importance of preventing respiratory infections and managing risk factors for cardiovascular disease. Vaccinations, such as the flu shot and pneumococcal vaccine, are recommended to reduce the risk of developing pneumonia and subsequent cardiovascular complications. Maintaining a healthy lifestyle, including proper hand hygiene, quitting smoking, and managing conditions like diabetes, high blood pressure, and high cholesterol, can also help lower the risk of infections and cardiovascular events.

Vaccinations can help prevent pneumonia and reduce the risk of stroke
Research has shown that respiratory infections, including flu and pneumonia, can elevate the likelihood of experiencing a heart attack or stroke. In particular, older adults are at a higher risk, with their chances of having a stroke increasing fourfold in the first 30 days after a pneumonia infection severe enough to require hospitalization.
The link between respiratory infections and stroke can be partially explained by the inflammatory response triggered by infections. This response increases the stickiness of platelets, promoting the formation of blood clots that can obstruct blood flow to the brain, resulting in a stroke.
Vaccinations, such as the flu shot and pneumococcal vaccine, are essential tools in preventing these infections and reducing the associated risk of stroke. For example, the pneumococcal vaccine offers protection against Streptococcus pneumoniae, a common cause of pneumonia. Additionally, the influenza vaccine can lower the risk of contracting the flu, which in turn reduces the chances of developing pneumonia.
Furthermore, vaccinations are especially crucial for individuals with heart disease, as they are at an increased risk of serious complications from the flu, including heart attacks and strokes. By staying up to date with recommended vaccinations, individuals can take a proactive step towards maintaining their health and reducing their risk of stroke.
