Family lawyers have long reported a seasonal rise in divorce and separation enquiries after the summer holidays, with some reporting up to a 30% increase in divorce enquiries during August and September, alongside a 10%–20% rise in visits to online separation advice pages. Across England and Wales, many family lawyers refer to September as the beginning of “divorce season”, as enquiries begin climbing after the school holidays. Online behaviour reflects the same trend, with the term “divorce” searched around 415,000 times in the UK over the past month, as thousands of people sought advice following relationship breakdowns.
Now, cardiologists are warning that while heartbreak is usually emotional, for a small number of people it can also become a genuine medical emergency.
Experts at Panthera Clinic say the intense emotional stress associated with divorce, bereavement, relationship breakdowns, and other life-changing events can, in rare cases, trigger Takotsubo cardiomyopathy, commonly known as broken heart syndrome. The condition temporarily weakens the heart muscle following a surge of stress hormones, producing symptoms almost identical to those of a heart attack, including chest pain, breathlessness, palpitations, and dizziness. Although many patients recover within weeks, broken heart syndrome can lead to heart failure, stroke, dangerous heart rhythm disturbances, and, in rare cases, death.
The condition affects an estimated 5,000 people in the UK each year. Around 90% of diagnosed cases occur in women, particularly those aged over 50, although anyone experiencing severe emotional or physical stress can develop it. Around 1 in 10 patients experience another episode after recovering, highlighting the importance of ongoing monitoring.
The warning comes as researchers prepare to launch the world’s first clinical trial investigating treatments specifically for the condition, a major milestone given that it has long had no targeted therapy.
Relationship experts say the weeks following the summer holidays often become a natural point for reassessing relationships. Extended time together, financial pressures, childcare during the school holidays, and returning to everyday routines can all expose existing tensions. Holiday romances also come to an end as people return home, while many couples postpone major relationship decisions until after summer.
Although heartbreak does not usually lead to broken heart syndrome, cardiologists say the end of a relationship is one of the condition’s most recognised emotional triggers.
7 moments that can put your heart under extreme stress
Dr Karen Faulkner, Associate Medical Director at Panthera Clinic, believes recognising periods of intense emotional or physical stress, and knowing when symptoms require emergency treatment, could save lives.
- Divorce or separation: The end of a long-term relationship is one of the most well-recognised emotional triggers for broken heart syndrome. The combination of grief, uncertainty, disrupted routines, and financial worries can create an intense stress response. Dr Faulkner said: “Following a breakup, prioritise sleep, regular meals, and staying connected with family or friends. If you experience sudden chest pain, breathlessness, or a racing heartbeat, don’t assume it’s ‘just heartbreak’, call 999 immediately.”
- The end of a summer romance: Holiday romances often develop quickly and intensely, making the emotional impact of returning home unexpectedly powerful. For some people, the sudden loss of excitement, companionship, and future expectations can trigger significant emotional stress. “Emotional distress after a breakup is normal, but if physical symptoms develop, particularly chest pain or feeling faint, seek urgent medical assessment rather than trying to wait it out.”
- Receiving life-changing bad news: Whether it’s redundancy, a serious diagnosis, financial difficulties, or unexpected family problems, sudden bad news can trigger an immediate release of stress hormones that temporarily affects how the heart functions. “Give yourself time to process major life events rather than trying to carry on as normal,” Dr Faulkner explained. “Seeking emotional support early can help reduce prolonged stress.”
- Family conflict after the holidays: Spending extended periods together during holidays can expose underlying tensions. Returning to work, financial pressures, and changing family routines can all add to emotional strain. “Persistent stress doesn’t just affect your mental well-being; it can also raise blood pressure and place additional strain on the cardiovascular system. Managing stress is part of protecting your heart health,” Dr Faulkner continued.
- Bereavement: Losing a loved one remains one of the most common emotional triggers for broken heart syndrome. The condition was originally recognised because of its association with profound grief. “Grief affects everyone differently. While overwhelming sadness is expected, severe chest pain, breathlessness, or collapse should never be attributed to grief alone.”
- Serious illness, surgery, or physical trauma: Broken heart syndrome isn’t only caused by emotional distress. Major operations, severe infections, asthma attacks, road traffic collisions, and other physical stresses can trigger the same hormonal response. “Patients recovering from major illness or surgery should report any new chest pain or sudden breathlessness immediately, even if they believe it’s part of recovery.”
- Even the happiest moments can overwhelm the heart: In rare cases, intensely joyful events, including weddings, surprise parties, becoming a grandparent, or winning the lottery, can trigger what’s known as “happy heart syndrome”. The heart doesn’t distinguish between positive and negative excitement; both can produce an overwhelming surge of adrenaline. Dr Faulkner said: “The risk remains extremely low, but it’s a reminder that sudden chest pain should never be ignored, regardless of whether it follows a happy or upsetting event.”
“More than a figure of speech”
Dr Faulkner continued: “People often talk about having a broken heart after a relationship ends, but for a small number of people it can be much more than a figure of speech. Late summer can be an emotionally challenging time for many people. We see relationships coming to an end after family holidays, summer romances drawing to a close, and people making significant life decisions as routines return to normal. While almost everyone experiences heartbreak without lasting physical effects, intense emotional stress can, in rare cases, temporarily weaken the heart muscle.
“Broken heart syndrome produces symptoms that are almost identical to a heart attack, including sudden chest pain, breathlessness, palpitations, and dizziness. It’s impossible to tell the difference without urgent medical assessment, which is why nobody should ever assume it’s simply stress or anxiety.”
The upcoming clinical trial offers hope that, for the first time, patients could eventually benefit from treatments designed specifically for the condition, rather than relying on standard heart failure therapies. “For decades we’ve recognised broken heart syndrome, yet we’ve had no treatments specifically designed for it. The launch of the first dedicated clinical trial is an exciting step towards understanding why some people develop the condition and how we might better treat it in future.”
“Whether chest pain follows the death of a loved one, the breakdown of a marriage, a stressful family holiday, or any other major emotional event, the message is always the same: treat it as a medical emergency until serious heart conditions have been ruled out,” Dr Faulkner added. “The heart and brain are far more closely connected than many people realise. As our understanding of cardiovascular disease continues to evolve, we’re learning more about how emotional stress can affect physical health. Recognising the symptoms and acting quickly could save lives.”
The warning comes as around 100,000 people are admitted to UK hospitals with a heart attack every year, roughly one every five minutes, while coronary heart disease continues to claim around 64,000 lives annually. As the summer draws to a close and relationship experts anticipate another busy period for separation enquiries, cardiologists hope greater awareness of broken heart syndrome will encourage more people to seek urgent medical attention when symptoms arise.
