Baseline Cardiovascular Risk Myomectomy vs Hysterectomy for Fibroids What the Study Shows
Fibroid surgery is often framed around bleeding, pain, fertility, uterine preservation, and recovery time. The linked study adds another layer that deserves attention: patients do not arrive at myomectomy and hysterectomy with the same cardiovascular risk profile.
That matters because baseline risk can affect anaesthesia planning, perioperative complications, long-term health counselling, and how researchers interpret outcomes after surgery. If one surgical group starts with more hypertension, diabetes, obesity, or lipid disorders, later differences in cardiovascular events may reflect pre-existing risk as much as the operation itself.
This article summarises the study’s practical message for clinical care. It is informational only and should not replace individual medical advice or local protocols.
What the study set out to compare
The study compared people undergoing surgery for uterine fibroids, focusing on two common options:
Myomectomy Uterus-sparing surgery that removes fibroids while leaving the uterus in place. It is often chosen when pregnancy is desired later, when uterine preservation is important, or when symptoms can be managed without removing the uterus.
Hysterectomy Definitive surgery that removes the uterus. It eliminates fibroid recurrence in the uterus and is often chosen when symptoms are severe, fertility is not desired, or other treatments have failed.
The key point was not simply which operation carries higher surgical risk. The study examined baseline cardiovascular risk before surgery, meaning the health status patients had before the operation took place.
This distinction is critical. A patient’s cardiovascular risk before myomectomy or hysterectomy may shape both short-term safety and long-term outcomes. It also helps clinicians avoid over-attributing later health events to the surgery when part of the risk was already present.
The main finding is that hysterectomy patients often start with higher cardiovascular risk
The study’s central finding was that patients undergoing hysterectomy for fibroids tended to have a less favourable cardiovascular risk profile than those undergoing myomectomy.
In practical terms, the hysterectomy group was more likely to have risk factors such as:
Higher age at the time of surgery
Hypertension
Diabetes or impaired glucose metabolism
Obesity
Dyslipidaemia
Smoking history, where captured
Other chronic medical conditions that increase perioperative risk
The myomectomy group, by contrast, generally included younger patients and those more likely to prioritise fertility or uterine preservation. Younger age alone lowers measured cardiovascular risk in most scoring systems, even when other risk factors are present.
That does not mean myomectomy patients have no cardiovascular risk. It means the two groups are not interchangeable at baseline.
The most clinically useful message from the study is that cardiovascular risk is not evenly distributed between fibroid surgery groups before the first incision is made.
This has a direct effect on research interpretation. If hysterectomy patients have more cardiometabolic disease before surgery, any crude comparison of outcomes after hysterectomy versus myomectomy may be misleading unless the analysis adjusts carefully for baseline differences.
Why these baseline differences make clinical sense
The pattern seen in the study fits real-world practice.
Myomectomy is more common among people who want to retain the option of pregnancy or preserve the uterus for personal reasons. These patients are often younger, though not always. Hysterectomy is more often chosen when symptoms are severe, fibroids are numerous or recurrent, medical treatment has failed, or fertility is no longer a goal.
Age is one of the strongest drivers of cardiovascular risk. With increasing age, the prevalence of hypertension, diabetes, abnormal lipids, and coronary artery disease rises. That makes an older hysterectomy cohort more likely to carry higher baseline risk even before surgical route, duration, or blood loss are considered.
Fibroids themselves also sit within a wider health context. They are common, affecting up to 70% to 80% of women by age 50 in many population estimates. Cardiovascular disease remains the leading cause of death worldwide, causing about 17.9 million deaths each year, according to global health estimates. In India, hypertension is also common, with national survey data suggesting that roughly one in five adult women has elevated blood pressure or is taking medicine for hypertension.
These background numbers explain why cardiovascular screening before benign gynaecological surgery is not a niche issue. A patient may present with heavy menstrual bleeding or pressure symptoms, but the preoperative visit may reveal untreated hypertension, diabetes risk, anaemia-related strain, or obesity-related anaesthetic concerns.
The risk factors that matter most before fibroid surgery
The study highlights the need to look beyond the uterus when planning fibroid surgery. A useful preoperative assessment should include both the gynaecological problem and the cardiometabolic profile.
Risk factor | Why it matters before surgery | How it may differ between groups |
Age | Strong predictor of cardiovascular risk and anaesthetic complications | Hysterectomy patients are often older |
Hypertension | Increases risk during anaesthesia and postoperative recovery | More common in older surgical cohorts |
Diabetes | Raises infection, wound, kidney, and vascular risk | May be more frequent in hysterectomy cohorts |
Obesity | Affects airway management, thrombosis risk, surgical difficulty, and recovery | Can affect both groups, often higher with age |
Dyslipidaemia | Marker of long-term vascular risk | More likely with increasing age and metabolic disease |
Smoking | Raises pulmonary, vascular, and wound risks | Needs active screening because it is often under-recorded |
Anaemia | Common in fibroid-related heavy bleeding and can strain the heart | Can occur in either group, especially with severe bleeding |
Anaemia deserves special attention. Severe fibroid bleeding can cause chronic iron deficiency. While anaemia is not a classic atherosclerotic risk factor like hypertension or diabetes, it can worsen fatigue, shortness of breath, tachycardia, and perioperative tolerance. In a patient with underlying heart disease, anaemia can increase physiological stress.
What this means for patient care and shared decision-making
The study should not be read as saying that hysterectomy is “worse” or that myomectomy is automatically “safer”. The finding is more nuanced. It shows that treatment groups differ before surgery, and those differences should be part of counselling.
For patients deciding between myomectomy and hysterectomy, the discussion should include:
Symptom severity
Desire for future pregnancy
Need for definitive treatment
Fibroid size, number, and location
Likelihood of recurrence after myomectomy
Route of surgery, such as open, laparoscopic, robotic, or vaginal where appropriate
Anaemia and bleeding risk
Baseline cardiometabolic health
Personal values around uterine preservation
A person with low cardiovascular risk may still choose hysterectomy if they want definitive treatment. A person with higher cardiovascular risk may still be a candidate for surgery if risk factors are identified and managed before the operation.
The practical question is not simply, “Which operation has lower cardiovascular risk?” A better question is, “What is this patient’s cardiovascular risk before surgery, and how should that shape planning?”
The phrase cardiovascular risk before myomectomy is especially relevant in younger patients because low age can create false reassurance. Younger patients may still have hypertension, diabetes, obesity, sleep apnoea, or a family history of premature cardiovascular disease. Screening should not be skipped because a patient is considering a uterus-sparing procedure.
How clinicians can assess risk more consistently
Cardiology, anaesthesia, and perioperative medicine guidelines generally support a structured approach rather than broad testing for everyone. Expert consensus from organisations such as the American College of Cardiology, American Heart Association, and obstetrics and gynaecology bodies favours assessment based on medical history, functional capacity, surgical risk, and active symptoms.
For fibroid surgery, a practical preoperative review should include the following.
Take a focused cardiovascular history
Ask about:
Chest pain, exertional breathlessness, palpitations, syncope, or leg swelling
Known hypertension, diabetes, kidney disease, stroke, or heart disease
Pregnancy-related hypertension or gestational diabetes
Family history of premature cardiovascular disease
Smoking and tobacco use
Current medicines, including anticoagulants, antiplatelets, antihypertensives, and diabetes medicines
Pregnancy-related conditions are especially important. A history of pre-eclampsia or gestational diabetes can signal higher future cardiovascular risk, even years later.
Measure rather than assume
Basic measurements can change the plan:
Blood pressure, repeated if high
BMI and waist-related risk where used
Haemoglobin and iron studies when bleeding is heavy
HbA1c or fasting glucose when diabetes risk is present
Lipid profile when age and risk history support testing
Renal function before major surgery or contrast-based imaging
ECG when indicated by age, symptoms, or medical history
Routine advanced cardiac testing is not needed for every patient. Testing should answer a clinical question. For example, new exertional chest pain before elective surgery should prompt evaluation. A healthy patient with good functional capacity and no symptoms may not need extensive cardiac work-up.
Use risk tools carefully
Risk calculators can help, but they have limits. Many tools were developed in specific populations and may not perfectly reflect Indian or multi-ethnic risk patterns. When available, clinicians can use region-calibrated cardiovascular risk charts or locally accepted perioperative risk tools.
The goal is not to reduce the patient to a score. The goal is to combine:
Surgical complexity
Route of surgery
Functional capacity
Active cardiac symptoms
Existing diagnoses
Lab findings
Patient goals
A low-risk laparoscopic procedure in a well patient is different from a complex open operation in someone with uncontrolled hypertension, diabetes, anaemia, and limited exercise tolerance.
Recommendations for healthcare providers
The study supports several changes in everyday practice.
Build cardiovascular screening into fibroid pathways
Risk assessment should not happen as a last-minute anaesthesia clearance form. It should begin when surgery becomes a realistic option. This allows time to treat anaemia, confirm blood pressure control, adjust diabetes medicines, and seek cardiology input when needed.
Compare surgical options only after adjusting for baseline risk
When counselling patients or reviewing evidence, clinicians should avoid simplistic claims that one procedure causes more cardiovascular events unless the data account for preoperative differences. Hysterectomy cohorts often include older and medically more complex patients.
Treat modifiable risk factors before elective surgery
Elective fibroid surgery creates an opportunity to improve health beyond the operation. Practical steps include:
Control high blood pressure before the procedure
Treat iron deficiency and anaemia
Improve glucose control where possible
Review lipid risk and long-term prevention needs
Encourage tobacco cessation
Assess thrombosis risk, especially in patients with obesity, immobility, prior clots, or major open surgery
Make counselling specific to the individual
Two patients with the same fibroid size may need different advice. One may be a 32-year-old planning pregnancy with well-controlled health markers. Another may be a 48-year-old with severe bleeding, high blood pressure, diabetes, and no desire for future fertility. The surgical discussion should reflect that full clinical picture.
What the study does not prove
The study’s baseline comparison is valuable, but it should not be stretched beyond its design. Baseline differences do not prove that hysterectomy causes higher cardiovascular risk. They show that the people selected for hysterectomy often already have more risk factors.
There may also be unmeasured influences, such as access to care, severity of bleeding, socioeconomic factors, race or ethnicity, prior pregnancy history, diet, physical activity, and differences in how diagnoses are recorded. These factors can shape both treatment choice and cardiovascular health.
For researchers, this means future studies should adjust carefully for baseline cardiometabolic risk, age, surgical route, fibroid severity, and social determinants of health. For clinicians, it means individual assessment remains essential.
The takeaway for fibroid surgery planning
The study’s message is clear: myomectomy and hysterectomy patients often differ before surgery begins. Hysterectomy patients tend to carry a higher burden of baseline cardiovascular risk factors, especially those linked with age and cardiometabolic disease. Myomectomy patients may be younger on average, but they still need proper screening.
For patient care, this means cardiovascular assessment should be part of fibroid surgery planning, not an afterthought. For decision-making, it means counselling should compare options in the context of the patient’s actual health profile. For healthcare providers, it means measuring and addressing risk early enough to change outcomes.
The best surgical choice is not based on the uterus alone. It is based on symptoms, fertility goals, anatomy, operative feasibility, and the whole-person risk profile brought into the operating theatre.
