Perimenopause, Palpitations and Takotsubo Syndrome: Understanding Heart Health During the Menopause Transition

Perimenopause and heart health

Source: The Conversation

This article explains how a racing heart and palpitations can occur during the menopause transition, and why they should not be automatically attributed to hormonal changes. It also covers Takotsubo syndrome, a rare but important condition that can resemble a heart attack, and provides clear guidance on when to seek medical care.

• Palpitations are common during perimenopause but not always due to hormones
• Takotsubo, or broken heart syndrome, can accompany palpitations and chest symptoms
• New or worsening palpitations warrant medical evaluation, with urgent care if chest pain or fainting occurs
• Diagnosis may involve ECG, blood tests, echocardiography, coronary angiography or MRI

Overview

The article from The Conversation discusses how a racing heart and palpitations are often reported during perimenopause, the transitional phase before menopause when hormonal levels fluctuate. While these symptoms can be related to hormonal changes, they should not automatically be assumed to be benign or exclusively hormone-driven. The piece emphasizes that palpitations can arise from multiple causes, including stress, anemia, thyroid disorders, abnormal heart rhythms, and long COVID. It also notes that a racing or irregular heartbeat can accompany a heart attack or another serious cardiac condition, underscoring the importance of proper assessment rather than dismissal as a normal part of aging.

Perimenopause and cardiovascular health

Perimenopause is defined as the transition before menopause when ovarian hormone levels fluctuate and menstrual cycles become less predictable. Menopause is reached after 12 consecutive months without a period. The article highlights that estrogen influences several aspects of cardiovascular health, including blood vessels, cholesterol and the body’s response to stress hormones. During the transition, some women may experience higher blood pressure, less favorable cholesterol profiles and abdominal fat accumulation. Insulin resistance may increase, affecting blood sugar control. These metabolic changes can contribute to longer-term cardiovascular risk, though age, genetics, existing conditions and lifestyle also shape heart health and cannot be attributed to hormones alone. The American Heart Association identifies the menopause transition as an important window to check blood pressure, cholesterol and blood sugar and to address risks early.

Broken heart syndrome (Takotsubo)

The article then delves into Takotsubo syndrome, a sudden but usually temporary change in how part of the heart muscle contracts. It most often affects the left ventricle and was first described in Japan in 1990. The name Takotsubo refers to a traditional Japanese octopus trap, because the left ventricle can temporarily balloon into a shape reminiscent of the trap. Triggers include intense emotional stress such as bereavement, shocking news, physical stress like severe illness, surgery or injury, and in some cases no trigger is evident. The precise cause remains uncertain, but a surge of stress hormones like adrenaline appears central, potentially affecting heart muscle cells, small vessels and the heart’s nervous signals. Takotsubo is rare, primarily affects postmenopausal women (about 90% of diagnosed patients), and studies commonly report an average age at diagnosis between 67 and 70. Palpitations can be a symptom, especially when paired with chest pain, breathlessness, dizziness, or fainting. Because these symptoms can mimic a heart attack, they should not be dismissed as part of perimenopause. The article also discusses whether lower estrogen levels may increase vulnerability, but notes that a direct causal link has not been established. In emergency settings, Takotsubo accounts for roughly 1–3% of suspected acute coronary syndrome cases, rising to about 5–6% among women presenting with suspected ACS.

Why it can look like a heart attack

The overlap of symptoms between Takotsubo and a heart attack presents a major diagnostic challenge. Both conditions can cause chest pain, shortness of breath, sweating, nausea, dizziness and fatigue. In Takotsubo, heart-muscle dysfunction is typically not explained by a blockage in a single coronary artery, though coronary artery disease can coexist and complicate diagnosis. Diagnostic tools include ECG, blood tests and echocardiography to monitor pumping function, coronary angiography to identify narrowed arteries, and cardiac MRI to provide detailed tissue images and help distinguish Takotsubo from inflammation or other conditions. In suspected cases, doctors often err on the side of caution and treat as a heart attack until a ruling is made.

Diagnosis and management

The article outlines standard diagnostic pathways used to differentiate Takotsubo from a heart attack, such as ECG and blood tests to detect heart muscle damage, echocardiography to assess pumping function, coronary angiography to assess major arteries, and MRI for detailed heart muscle imaging. It also notes that heart function often improves within days to weeks, and many patients recover well, though some may experience lasting symptoms or less complete long-term recovery. The article emphasizes the importance of timely medical evaluation for new or worsening palpitations and for symptoms suggesting a cardiac event, as delays can worsen outcomes.

When to seek medical help

In the United Kingdom, the article advises calling 999 for sudden chest pain or discomfort that does not go away, tightness or squeezing, pain spreading to the arms, neck, jaw, stomach or back, along with sweating, nausea, light-headedness or breathlessness. For severe difficulty breathing or if someone collapses, call 999 and do not drive to the hospital. While palpitations during perimenopause are common and often have non-serious causes, new, persistent or worsening episodes should be assessed by a healthcare professional, and heart attack and Takotsubo cannot be distinguished based on symptoms alone.

Bottom line

The article concludes that palpitations during perimenopause are common and often due to non-serious causes, but changes in symptom patterns warrant medical evaluation. It also highlights that Takotsubo syndrome, though rare, is an important differential diagnosis in older women and can resemble heart attack in presentation, making appropriate diagnostic testing essential. The menopause transition represents an opportunity to screen for cardiovascular risk and to implement early risk-reduction strategies.
