Due to 'too much happiness,' woman ends up in ER

The phrase 'I could die of happiness' took on a literal meaning for a 65-year-old woman who was rushed to the emergency room after experiencing chest pain and shortness of breath. The unusual case, detailed in the Oxford Medical Case Reports, revealed that the woman's symptoms, which began three days after her daughter's wedding celebration, mimicked a heart attack. Doctors noted reduced blood flow to her heart, typically associated with blood clots, but found no such blockage. Instead, her left ventricle showed a balloon-like expansion, weakening the heart and impairing its ability to pump blood effectively. This condition, known as Takotsubo cardiomyopathy (TTS), is a rare syndrome triggered by sudden, intense emotional experiences, whether positive or negative. While often referred to as 'broken heart syndrome' when caused by distress, the 'happy heart syndrome' variant occurs from overwhelming positive emotions. TTS can temporarily alter the heart's shape, resembling Japanese octopus traps, hence its name. Although reversible, TTS can be life-threatening. Researchers estimate that 1-3% of patients suspected of having a heart attack without a clot may actually have TTS. The proportion caused by positive emotions is even smaller, around 4%, suggesting it may be underdiagnosed. First described in Japan in 1983, the exact mechanisms are still being studied, but it involves the activation of the sympathetic nervous system and a surge in catecholamines.
