Gi Bleed And Stroke: Is There A Link?

Gastrointestinal (GI) bleeding is a known complication of acute ischaemic stroke, with an incidence of 0.1-8% depending on the population studied. GI bleeding can increase the risk of death in stroke patients, with one study finding that 81% of stroke patients with GI bleeding died in hospital or were severely dependent, compared to 41% of those without GI bleeding. However, the incidence of GI bleeding in stroke patients appears to be decreasing, possibly due to the increased use of prophylactic medications that reduce gastric acid.

Gastrointestinal bleeding is a well-known complication during the acute phase of a stroke

Gastrointestinal (GI) bleeding is a recognised complication of acute stroke, with an incidence of 0.1-8.0% depending on the population studied. The Fukuoka Stroke Registry, a multicentre, hospital-based registry, found that 1.4% of 6,529 patients with acute ischemic stroke experienced GI bleeding. A separate study of 6,853 people who had ischemic strokes found that 1.5% had GI bleeding.

GI bleeding is a potentially serious complication of acute stroke and has been associated with poor clinical outcomes, including neurological deterioration, in-hospital mortality, and poor functional outcomes. In a study of 6,853 people who had ischemic strokes, those with GI bleeding were more than three times more likely to die during their hospital stay or be severely dependent on others for their care at the time they left the hospital than people who did not have GI bleeding.

Several risk factors for post-stroke GI bleeding have been identified, including advanced age, a history of peptic ulcer or previous GI bleeding, admission stroke severity, and impaired level of consciousness. However, no reliable or validated scoring system is currently available to predict GI bleeding after acute stroke. The development of such a scoring system could help identify vulnerable patients and allocate relevant medical resources.

The pathophysiological mechanisms underlying the association between acute stroke and GI bleeding are not fully understood. One hypothesis is that acute massive blood loss from GI bleeding results in systemic vasoconstriction, particularly in cerebral vessels, increasing the risk of ischemic stroke. Another hypothesis is that cerebral ischemia and reperfusion injury are caused by acute blood loss and subsequent blood transfusion.

The incidence of gastrointestinal bleeding after a stroke is decreasing

Gastrointestinal (GI) bleeding is a recognised complication of acute stroke, with an incidence of 0.1-8.0% depending on the population studied. However, recent studies have shown a decreasing trend in the occurrence of GI bleeding after a stroke. This could be attributed to various factors, including improved sanitary conditions, infection eradication, and the use of acid-suppressing medications.

Causes of GI Bleeding

GI bleeding can occur due to various factors, including:

• Peptic ulcer
• Helicobacter pylori infection
• Use of non-steroidal anti-inflammatory drugs (NSAIDs)
• Anticoagulants
• Stress ulcers
• Mallory-Weiss syndrome
• Angiodysplasia of the colon
• Pancreatic cancer
• Duodenal ulcers
• Gastric ulcers

Risk Factors for GI Bleeding

Several risk factors have been identified that increase the likelihood of GI bleeding after a stroke:

• Advanced age
• History of peptic ulcer
• Infection
• Severe neurological deficit
• Low Glasgow Coma Scale (GCS) score
• Posterior circulation infarction
• Atrial fibrillation
• History of hypertension
• Digestive tract disease
• Renal dysfunction
• Coagulation disorders
• Water electrolyte imbalance
• Cancer
• Liver disease
• Chronic pulmonary disease
• Hyperthyroidism
• Arrhythmia
• Iron deficiency anaemia
• Alcoholism
• Obesity
• Depression

Clinical Outcomes of GI Bleeding after Stroke

GI bleeding after a stroke is associated with poor clinical outcomes, including:

• Neurological deterioration
• In-hospital mortality
• Poor functional outcome
• Increased 1-year mortality
• Higher disability level
• Prolonged hospital stay
• Discontinuation of antithrombotic treatment

The risk of death increases for stroke patients who develop gastrointestinal bleeding

Gastrointestinal (GI) bleeding is a well-known complication that can occur during the acute phase of a stroke, with an incidence of 0.1-8.0% depending on the population studied. The risk of death increases for stroke patients who develop gastrointestinal bleeding.

A study published in the online issue of Neurology, the medical journal of the American Academy of Neurology, found that people who have gastrointestinal bleeding after a stroke are more likely to die or become severely disabled than stroke sufferers with no GI bleeding. The study involved 6,853 people who had ischemic strokes. Of those, 829 people died during their hospital stay and 1,374 had died within six months of the stroke. A total of 100 people, or 1.5 percent, had gastrointestinal bleeding, or bleeding in the stomach or intestines, while they were in the hospital from the stroke. In more than half of the cases, the GI bleeding occurred in people who had mild to moderate strokes. The people with GI bleeding were more than three times more likely to die during their hospital stay or be severely dependent on others for their care at the time they left the hospital than people who did not have GI bleeding. A total of 81 percent of those with GI bleeding died in the hospital or were severely dependent, compared to 41 percent of those without GI bleeding. Those with GI bleeding were also 1.5 times more likely to have died within six months after the stroke than those without GI bleeding. Of those with GI bleeding, 46 percent had died within six months, compared to 20 percent of those without GI bleeding. This relationship remained even after researchers adjusted for other factors, including other conditions such as pneumonia and heart attack.

Another study, published in BMC Gastroenterology, developed and validated a risk model (acute ischemic stroke-associated gastrointestinal bleeding score, the AIS-GIB score) to predict in-hospital GI bleeding after acute ischemic stroke. The AIS-GIB score was developed from data in the China National Stroke Registry (CNSR). The overall in-hospital GI bleeding after AIS was 2.6%, 2.3%, and 1.5% in the derivation, internal, and external validation cohorts, respectively. An 18-point AIS-GIB score was developed from the set of independent predictors of GI bleeding including age, gender, history of hypertension, hepatic cirrhosis, peptic ulcer or previous GI bleeding, pre-stroke dependence, admission National Institutes of Health stroke scale score, Glasgow Coma Scale score, and stroke subtype (Oxfordshire). The AIS-GIB score showed good discrimination in the derivation, internal, and external validation cohorts.

GI bleeding is a serious complication that can occur after a stroke, and it is associated with increased mortality and disability. The AIS-GIB score is a valid clinical grading scale that can be used to predict the risk of in-hospital GI bleeding after AIS.

Upper gastrointestinal bleeding is a common emergency condition in digestive diseases

Upper gastrointestinal (GI) bleeding is a common emergency condition in digestive diseases. It is a potentially serious complication of acute stroke, with an incidence of 0.1-8.0% depending on the population studied. The risk of upper GI bleeding is higher in patients with a history of peptic ulcers, severe neurological impairment, and atrial fibrillation. It can lead to severe health complications, including hemodynamic instability, shock, and even death.

The causes of upper GI bleeding vary and include peptic ulcers, gastritis, esophagitis, varices in the esophagus or stomach, Mallory-Weiss tears, and benign tumors or cancer. The most common causes of peptic ulcers are Helicobacter pylori (H. pylori) infection and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and blood thinners. Upper GI bleeding typically presents as hematemesis (vomit containing blood) or melena (dark, black, and tarry feces).

The management of upper GI bleeding involves resuscitation, supportive therapy, and addressing the underlying cause. Patients with hemodynamic instability, continuous bleeding, or a high risk of morbidity/mortality require intensive care and frequent monitoring. Most patients with upper GI bleeding require hospitalization, and some may need blood transfusions, platelet transfusions, or prothrombin complex concentrate transfusions.

Upper GI bleeding is a serious condition that requires prompt evaluation and treatment to prevent adverse outcomes. It is a common emergency condition in digestive diseases and can lead to severe health complications if not managed effectively.

The incidence of gastrointestinal bleeding after an acute ischemic stroke is 1%-5%

The Incidence of Gastrointestinal Bleeding After an Acute Ischemic Stroke

Gastrointestinal (GI) bleeding is a well-known complication that may occur during the acute phase of a stroke, with an incidence of 0.1-8.0% depending on the population studied. The Fukuoka Stroke Registry, a multicenter, hospital-based registry in Japan, reported an incidence of 1.4% among 6,529 patients with acute ischemic stroke registered between June 2007 and December 2012. Another study using the Registry of the Canadian Stroke Network reported a similar incidence of 1.5%.

The China National Stroke Registry, the largest stroke registry in China, reported a slightly higher incidence of 2.6% among 14,702 patients with acute ischemic stroke enrolled between September 2007 and August 2008. The risk of GI bleeding after an acute ischemic stroke varies across different populations and settings, with reported rates ranging from 1.24% to 8.1% in various studies.

Risk Factors and Clinical Outcomes

Several risk factors have been identified for GI bleeding after an acute ischemic stroke, including advanced age, history of peptic ulcer or previous GI bleeding, admission stroke severity, impaired level of consciousness, and middle cerebral artery territory ischemia. Male gender, hypertension, hepatic cirrhosis, and posterior circulation stroke have also been associated with an increased risk of GI bleeding.

GI bleeding after an acute ischemic stroke is associated with poor clinical outcomes, including neurological deterioration, in-hospital mortality, and poor functional outcome. Patients with GI bleeding are more likely to experience neurologic deterioration, require blood transfusions, and have higher rates of in-hospital death and long-term disability.

Prevention and Prophylaxis

The use of histamine-2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs) is recommended for the prevention of peptic ulcers and GI bleeding, especially in high-risk patients. These medications can effectively reduce gastric acid and lower the risk of GI bleeding in patients on antithrombotic therapy or nonsteroidal anti-inflammatory drugs (NSAIDs). However, the optimal GIB prevention strategies for patients with acute ischemic stroke are still unclear.

GI bleeding is a potentially serious complication of acute ischemic stroke, with an incidence of 1%-5% depending on the population. It is associated with poor clinical outcomes and increased risk of stroke recurrence. Identifying risk factors and implementing prophylactic strategies, such as the use of H2RAs or PPIs, may help reduce the incidence and improve outcomes in vulnerable patients.
