Total hip replacement is one of the most common non-emergency surgeries. The number of yearly hip replacements performed in the United States is expected to rise to
Hip replacements are commonly used to treat conditions like arthritis and hip fractures that cause pain and stiffness. The risk of serious complications following a hip replacement is generally low, but all surgeries come with some risk.
Heart attack and other serious cardiovascular complications are possible complications of joint replacement surgeries. The risk of having a heart attack is highest in people with a history of cardiovascular disease and becomes higher with
Read on to learn more about the link between hip replacement surgery and heart attacks, including how common heart attacks are after hip surgery, risk factors, and things you can do to prevent them.
A total hip replacement is one of the most successful orthopedic surgeries, with more than a
The reported 30-day incidence of heart attack ranges from
Why does hip replacement surgery increase the risk of a heart attack?
It’s not exactly clear why your risk of having a heart attack increases after major surgery, but various factors are likely at play.
Some events during surgery may increase stress on your heart. These include:
- disruption of blood flow
- undergoing general anesthesia
- surgical trauma
Inflammation caused during the repair process can increase your blood’s chances of clotting, which can increase your risk of heart problems. Increased heart rate and elevation in blood pressure can put stress on your
With orthopedic surgery, there’s also a risk of developing a fat embolism or cement embolism. That’s when fat or cement from the joint replacement gets released into the bloodstream, causing a blockage or clot. This can cause serious problems with your
Changes in medications before the surgery, like discontinuing low dose aspirin, may contribute as well.
How common are heart attacks after surgery?
One in 5 people over 65 or over 45 with a history of cardiovascular disease develop one or more MACE within a year of non-cardiac surgery.
How long is the risk elevated?
Your risk of developing a heart attack remains elevated in the period directly after your surgery, especially in the first week.
In a large
While your risk of a heart attack may decrease after a few weeks, you should still be aware of some other risks. Decreased mobility after hip surgery
Risk after hip replacement compared to other joint replacements
- More than
90 percentof hip fractures occur in people over the age of 65.
- Studies have found that rates of major cardiac complications after joint replacement surgeries are as low as
0.2 to 0.8 percent.
- Heart attacks occur in about
3 percentof people undergoing major non-cardiac surgery.
- The 30-day mortality rate for people with at least one cardiovascular risk factor undergoing major surgery is
0.5 to 2 percent, and heart attack is the most common cause of death.
- Most complications seem to occur within 30 days of surgery and particularly in the first week.
There’s still a
In evaluating your risk prior to surgery, your doctor will consider
- overall health and underlying conditions
- cardiovascular health
- respiratory health
- blood pressure
- complete blood count
You may undergo several tests as part of the assessment, including:
- physical exam
- chest X-ray
- blood and urine tests
Your doctor may recommend taking medications like statins or beta-blockers leading into your surgery. They may also tell you to reduce or quit smoking and drinking.
Online tools are available to help you assess your risk, but you should always consult with your doctor.
Doctors don’t usually recommend a hip replacement unless your hip is worn to the point it doesn’t respond to physical therapy or steroid injections. It’s almost always an elective surgery. That means it’s not mandatory but performed to improve function and reduce pain.
A promising but developing alternative to a hip replacement for treating osteoarthritis is stem cell injections. These injections contain stem cells that can become cartilage, muscle, or bone. It’s thought that they could help regenerate lost cartilage in your hip.
Some conditions that can cause hip pain, like autoimmune arthritis and osteoporosis, are associated with an increased risk of developing a heart attack. But research is yet to show that the conditions are responsible for the higher risk.
Studies that look at the prevalence of diseases in large populations have found an observational link between osteoporosis and cardiovascular disease, partly because of shared risk factors like aging.
Researchers have found that the risk of heart attack increases after having a hip replacement. The risk seems to be highest in the month, and particularly in the week, following surgery.
Heart attacks and other surgical complications that affect the heart become more common with advanced age. They’re also more common in people with a history of cardiovascular disease.
It’s important to talk with your doctor before your surgery to evaluate your risk of complications and develop a plan to minimize your risk.
