An aneurysm can form in the heart when part of the heart wall or a blood vessel connected to it weakens and bulges outward. Yes, you can have an aneurysm in your heart, and it can pose serious health risks if not detected and treated.
This condition may follow a heart attack, affect the aorta, or involve the lower pumping chambers of the heart.
You may not always notice symptoms immediately, but when they appear, they can resemble a heart attack or other heart-related issues. Chest pain, shortness of breath, or irregular heartbeats can signal that something is wrong.
You can develop an aneurysm in the heart itself or in the major artery connected to it. These weak spots may form in the heart’s muscle after damage or in the aorta, the largest artery carrying blood from your heart to the rest of your body.
Both can affect your health in different ways.
A heart aneurysm is a bulge that develops in the wall of the heart muscle. It usually happens when the heart tissue becomes weak after a heart attack.
The damaged area loses strength, and over time, it may balloon outward. Most heart aneurysms occur in the left ventricle, the chamber that pumps oxygen-rich blood to your body.
This type is called a ventricular aneurysm. You may not notice symptoms right away.
When they do appear, they can include chest pain, irregular heartbeat, or shortness of breath. In some cases, blood clots can form inside the aneurysm and increase the risk of stroke.
Treatment depends on the size, symptoms, and risk factors. Options may include medicines to reduce strain on the heart or surgery if the aneurysm threatens your safety.
A ventricular aneurysm forms in the heart muscle itself, typically following a heart attack that weakens the tissue. An aortic aneurysm develops in the wall of the aorta, the large artery that carries blood away from your heart.
The two conditions differ in location and risk. A ventricular aneurysm rarely ruptures but can cause blood clots or heart rhythm problems.
An aortic aneurysm, however, can rupture, leading to severe internal bleeding and often life-threatening emergencies. There are two main types of aortic aneurysms:
Understanding which type you have is essential because the treatments and risks associated with each type differ.
Heart aneurysms are less common than aortic aneurysms. Among heart aneurysms, the left ventricular aneurysm is the most frequent type.
It usually develops in people who have had a significant heart attack. Right ventricular aneurysms are rare.
They may be associated with certain heart conditions, but are not commonly seen in the general population. Aortic aneurysms are more common overall.
Abdominal aortic aneurysms are especially frequent in older adults, particularly men over 65 who smoke or have high blood pressure. Thoracic aortic aneurysms are less common but still a serious concern.
| Type | Location | Risk |
| Ventricular aneurysm | Heart wall (usually the left ventricle) | Clots, arrhythmia, reduced pumping ability |
| Abdominal aortic aneurysm | Lower aorta (abdomen) | High risk of rupture if large |
| Thoracic aortic aneurysm | Upper aorta (chest) | Risk of rupture may affect the aortic valve |
Different aneurysms affect the heart and nearby blood vessels in unique ways. Some develop inside the heart muscle itself, while others occur in the aorta, the body’s largest artery.
Each type carries specific risks and may require different approaches to monitoring and treatment.
A ventricular aneurysm usually forms in the left ventricle after a heart attack. When part of the heart muscle is damaged, the weakened area can bulge outward as blood pumps through.
This bulge does not typically rupture like other aneurysms, but it can still lead to serious problems. You may not notice symptoms if the aneurysm is small.
Larger ones can cause chest pain, shortness of breath, or irregular heartbeats. Blood clots may also form inside the aneurysm, raising the risk of stroke or blocked arteries.
Diagnosis often involves imaging tests such as echocardiograms or CT scans. Treatment depends on size and symptoms.
Options may include medication to reduce strain on the heart, blood thinners to prevent clots, or surgery if the aneurysm interferes with heart function.
An ascending aortic aneurysm develops in the first part of the aorta, near where it leaves the heart. This section of the artery handles very high pressure, so a bulge here can be dangerous if it grows unchecked.
Risk factors include high blood pressure, genetic conditions like Marfan syndrome, and a history of smoking. Many people do not notice symptoms until the aneurysm becomes large.
When symptoms do occur, they may include chest pain, hoarseness, or shortness of breath. Doctors often monitor the aneurysm with imaging tests.
Surgery may be recommended if the tumor reaches a specific size or grows rapidly. Repair usually involves replacing the weakened section of the aorta with a graft.
An abdominal aortic aneurysm (AAA) occurs in the lower part of the aorta, below the chest. This is one of the most common types of aortic aneurysm.
It often develops slowly and without symptoms. If the aneurysm enlarges, you might feel a pulsing sensation in your abdomen or notice back pain.
The greatest danger is rupture, which causes sudden internal bleeding and requires emergency care. Screening is essential, especially if you are over 65, have smoked, or have a family history of AAA.
Treatment may involve regular monitoring for smaller aneurysms or surgery for larger ones. Endovascular repair, a minimally invasive procedure, is often used to reinforce the weakened artery wall.
An aortic dissection is not a true aneurysm but a related condition. It happens when the inner layer of the aorta tears, allowing blood to flow between the layers of the vessel wall.
This creates a false channel and weakens the artery. Symptoms usually appear suddenly and may include sharp chest or back pain, fainting, or stroke-like signs.
Aortic dissection is a medical emergency that requires immediate treatment. Doctors classify dissections by location.
A tear in the ascending aorta typically requires urgent surgery, whereas a tear in the descending aorta may sometimes be managed with medication and close monitoring. Early detection and rapid care are critical to survival.
Several factors increase your risk of developing an aneurysm in or near the heart. The most important include conditions that weaken artery walls, habits that damage blood vessels, and inherited traits that affect the strength of connective tissue.
High blood pressure puts constant force on your artery walls. Over time, this pressure can cause them to stretch, thin, or bulge.
If left untreated, the risk of an aneurysm forming increases. High cholesterol also plays a role.
When cholesterol builds up, it can form plaques that harden the arteries, a process known as atherosclerosis. Hardened arteries lose their flexibility, making them more likely to develop weak spots.
Together, high blood pressure and high cholesterol create a higher chance of an aneurysm by damaging vessel walls and limiting healthy blood flow.
Key points:
Smoking is one of the strongest risk factors for aneurysms. Chemicals in tobacco weaken the structure of blood vessels and speed up atherosclerosis.
Studies show that most abdominal aortic aneurysms are linked to a history of smoking. Other lifestyle habits also raise risk.
A diet high in saturated fats and low in fruits and vegetables can lead to elevated cholesterol levels. Lack of physical activity contributes to poor circulation and higher blood pressure.
Excessive alcohol use and unmanaged stress can also strain your cardiovascular system. Making changes such as quitting smoking, eating balanced meals, and exercising regularly can lower your risk.
Risk-increasing habits:
Your family background matters. If close relatives have had aneurysms, your chances of developing one are higher.
This risk is particularly pronounced when multiple family members are affected. Certain inherited conditions also weaken connective tissue in arteries.
Examples include Marfan syndrome and Ehlers-Danlos syndrome. These disorders make artery walls more fragile and prone to bulging.
Even without a known genetic disorder, a family history of aneurysms or heart disease should prompt regular checkups and possible screening. Early detection is essential if you have these risk factors.
Conditions linked to higher risk:
An aneurysm in or near the heart can cause noticeable discomfort, remain silent for years, or lead to a sudden medical emergency if it ruptures. The way it presents itself often depends on its size, location, and whether it has weakened the vessel wall enough to cause a leak or rupture.
One of the most common warning signs of a heart-related aneurysm is chest pain or pressure. You may feel this pain in the center or left side of your chest, and it can spread to your back, shoulder, or jaw.
The discomfort often feels steady rather than sharp. Shortness of breath may also occur, especially if the aneurysm presses against nearby structures, such as the airways or heart chambers.
Some people notice a pulsating sensation in the chest, which can feel like a heartbeat that is stronger or more irregular than usual. Other possible signs include:
These symptoms do not confirm the presence of an aneurysm on their own, but they should not be ignored.
Many heart and aortic aneurysms cause no symptoms at all. This is why they are often referred to as a “silent killer.”
You may live with one for years without knowing it, even if it is large.
Unruptured aneurysms are often found during imaging tests for other health issues. For example, a CT scan or echocardiogram done for chest pain or lung problems may reveal an aneurysm by chance.
Risk factors play a key role in whether you should be screened. These include:
Regular checkups and imaging may be the only way to detect an aneurysm before it becomes dangerous.
A ruptured aneurysm is a life-threatening medical emergency. When this happens, the weakened blood vessel wall tears open, causing sudden internal bleeding.
The most common sign is severe, tearing chest or upper back pain that comes on quickly. You may also experience dizziness, faintness, or shock due to a rapid drop in blood pressure.
Other possible signs include:
If you experience these symptoms, call emergency services immediately. A rupture requires urgent treatment, which may include open surgery or endovascular repair to stop the bleeding and stabilize circulation.
Detecting an aneurysm in or near the heart relies on imaging technology and careful evaluation of your risk factors. Doctors use different tests to look at the aorta and surrounding vessels.
Some people may need screening even if they do not have symptoms.
A CT scan is one of the most commonly used diagnostic tools in emergencies. It creates detailed images of the chest, abdomen, and pelvis, often with contrast dye to highlight blood flow.
CT scans can quickly show the size and location of an aneurysm.
MRI provides clear pictures without radiation. It is helpful for long-term monitoring of a stable aneurysm.
However, it takes longer than a CT scan and is not usually the first choice during urgent situations.
An ultrasound test is often used for abdominal aortic aneurysms. It is painless, uses sound waves, and does not involve radiation.
A transthoracic echocardiogram (TTE) can check the aortic root and ascending aorta. A transesophageal echocardiogram (TEE) gives a closer look at the entire aorta but requires sedation.
CT scans are fast and accurate in emergencies. MRI is better suited for follow-up, while ultrasound is a straightforward, safe, and simple option for screening.
An angiogram uses X-rays and contrast dye to show blood vessels in detail. It can outline the shape of the aorta and pinpoint an aneurysm.
This test is less common as a first step because CT and MRI often provide enough information. Doctors may use an angiogram when planning surgery or a stent procedure.
It helps measure the exact size of the aneurysm and shows how close it is to essential branches of the aorta.
The test requires inserting a catheter into a blood vessel, usually through the groin. Because it is invasive and carries some risk, it is not used for routine screening.
Instead, it plays a specialized role in treatment planning.
Screening is not recommended for everyone. Instead, it focuses on people with a higher risk.
Men over 65 who have smoked are often advised to get a one-time abdominal ultrasound. Women over 75 with a smoking history may also benefit.
If you have a close relative with an aneurysm, your doctor may suggest screening even if you have no symptoms. Family history increases your risk, especially for thoracic aortic aneurysms.
Screening can detect an aneurysm before it causes problems. By identifying it early, you and your doctor can determine whether regular monitoring, lifestyle changes, or treatment is necessary.
Treatment depends on the type of heart aneurysm, its size, and whether it has ruptured. You may need surgery, medication, or close monitoring.
Preventing growth or rupture also involves making long-term changes to your daily habits, including a balanced diet, regular exercise, and avoiding risk factors such as smoking.
If your aneurysm is small and not causing symptoms, your doctor may recommend regular imaging tests to watch for changes. This is often referred to as monitoring or watchful waiting.
Medications can help lower blood pressure and reduce strain on your arteries. Beta-blockers and ACE inhibitors are commonly prescribed to slow aneurysm growth.
For larger or symptomatic aneurysms, surgery is often necessary. Open surgery involves replacing the weakened section of the artery with a graft.
Endovascular repair involves placing a stent graft through a catheter, which is a less invasive approach that may facilitate quicker recovery.
| Approach | When Used | Key Benefit |
| Monitoring | Small, stable aneurysms | Avoids unnecessary surgery |
| Medications | High blood pressure or risk factors | Slows aneurysm growth |
| Open surgery | Large or ruptured aneurysms | Durable, long-term repair |
| Endovascular repair | Suitable anatomy, high surgical risk | Less invasive, shorter recovery |
A ruptured aneurysm is a life-threatening emergency. If this happens, you need immediate hospital care.
Symptoms may include sudden, severe chest or abdominal pain, rapid heartbeat, and fainting. Emergency surgery is the only option to stop bleeding.
In most cases, doctors perform either open repair or endovascular repair, depending on your condition and the location of the rupture.
Survival depends on how quickly you receive treatment. Calling 911 without delay is critical.
Even with surgery, recovery can be challenging, and long-term follow-up is necessary to monitor heart and vascular health.
A healthy lifestyle plays a significant role in preventing aneurysm growth and lowering the risk of rupture. You should avoid smoking, limit your alcohol consumption, and maintain a balanced diet rich in fruits, vegetables, and whole grains.
Regular exercise helps control blood pressure and weight. Low- to moderate-intensity activities, such as walking, swimming, or cycling, are generally safe.
Avoid heavy lifting or intense straining, as this can cause a sudden increase in blood pressure.
Routine medical check-ups and imaging tests help track changes in your aneurysm. By combining lifestyle adjustments with medical care, you reduce the chance of complications and improve your overall cardiovascular health.
Aneurysms can form in blood vessels outside the heart and aorta. Some of these conditions are rare but can still cause serious health problems if not detected and treated in time.
A cerebral aneurysm develops in the arteries of your brain. It occurs when a weak spot in the vessel wall bulges outward, often described as a balloon-like swelling.
Many people never notice symptoms until the aneurysm leaks or ruptures. When rupture happens, it can cause a type of bleeding stroke called a subarachnoid hemorrhage.
This is a life-threatening emergency. Warning signs may include sudden severe headache, nausea, vision changes, or loss of consciousness.
Doctors often use CT scans, MRIs, or cerebral angiography to detect these aneurysms. Treatment depends on the size and risk of rupture.
Options include surgical clipping or endovascular coiling, which seal off the weakened vessel.
Managing blood pressure, avoiding smoking, and regular check-ups are essential steps if you are at higher risk due to family history or other conditions.
A mesenteric artery aneurysm affects the arteries that supply blood to your intestines. These aneurysms are uncommon but can be dangerous because rupture leads to severe internal bleeding and abdominal pain.
You may not feel symptoms until the aneurysm grows large or bursts. In some cases, people notice vague abdominal discomfort or digestive issues.
Due to their location, these aneurysms are often discovered by chance during imaging for other conditions.
Key risks include:
Treatment usually involves surgical repair or endovascular stenting if the aneurysm is large, symptomatic, or at risk of rupture. Smaller aneurysms may be monitored with regular imaging.
A splenic artery aneurysm is the most common type of visceral artery aneurysm. It forms in the artery that supplies blood to your spleen.
Women, especially during pregnancy, are at higher risk of complications from this condition. Most splenic artery aneurysms cause no symptoms.
When symptoms appear, they may include abdominal pain, nausea, or shoulder pain from referred discomfort. A rupture can cause sudden and severe bleeding, which requires urgent medical attention.
Doctors often diagnose these aneurysms with ultrasound, CT, or MRI scans.
Treatment depends on size and risk factors:
Managing blood pressure and avoiding smoking can help reduce the risks of growth or rupture.
Heart aneurysms, while less common than aortic aneurysms, can still pose serious risks to your health if left untreated. Because symptoms often mimic other heart issues—or remain silent altogether—early detection through screening and imaging is essential. By knowing the differences between heart and aortic aneurysms, understanding risk factors like high blood pressure, smoking, and family history, and recognizing possible warning signs, patients can take proactive steps to protect themselves. Treatment ranges from lifestyle changes and medications to advanced surgical repairs, depending on the severity and location of the aneurysm. The key is not waiting for symptoms to worsen but working closely with a cardiovascular specialist to monitor your condition and plan ahead for the best outcomes.
