Mary, a lively business woman, wakes up one morning and notices something odd. She feels warmer than usual, not just a little warm, but a strange kind of heat that doesn’t go away. She has no cold or flu symptoms, yet her body temperature rises and doesn’t settle. Worried, Mary visits the clinic, sensing something deeper. Could her heart be sending a secret message?
The Heart’s Silent Signal: Fever from Within
Many don’t realize that heart problems can indeed affect body temperature.
Medical studies reveal that fever, more than just a sign of infection, can sometimes be caused by cardiac issues such as endocarditis (infection inside the heart), pericarditis (inflammation of the heart’s outer lining), and fever following heart attacks or cardiac surgery. For example, endocarditis is associated with fever in 90% of cases, making it a crucial sign for diagnosis.
After a heart attack, it’s not uncommon for the body to develop a fever as an inflammatory response to heart tissue damage. Around 25-50% of these patients experience high body temperatures. Inflammation triggers immune responses that raise body temperature, a natural defense mechanism but one that requires careful medical attention.
How Does This Affect You?
If you have a fever above 38°C following heart symptoms, this can signal complications and should prompt you to seek medical help immediately. Especially if accompanied by chest pains or breathing difficulties, it could mean pericarditis or other serious conditions requiring hospitalization.
The Science Behind Heart and Temperature
Our body’s thermostat, the hypothalamus, controls temperature by adjusting blood flow and shivering to maintain balance. Heart function, blood flow, and inflammation significantly influence this balance, explaining why heart problems sometimes relate to body temperature changes.
Moreover, when body temperature rises, the heart rate increases. Studies note an average rise of approximately 6-7 beats per minute with each degree Celsius increase in temperature. This means your heart is working harder during a fever.
Protect Your Heart, Listen to Your Body
- Persistent fever can stem from heart conditions though it’s rare.
- Key heart issues linked to fever include endocarditis, pericarditis, and post-heart attack inflammation.
- Fever following heart injury signals inflammatory healing or possible infection.
- Body temperature elevation causes heart rate increases, indicating extra stress on the heart.
- Prompt medical consultation is vital when fever and heart symptoms coexist.

FAQs:
Can heart problems affect body temperature?
Yes, infections like endocarditis and inflammation from heart conditions can cause fever, alerting us to cardiac issues (Dtsch Arztebl Int. 2018).
How does high temperature affect the heart?
Every degree Celsius rise in body temperature increases heart rate by about 6-7 bpm, making the heart work harder (Scand J Trauma Resusc Emerg Med. 2015).
Does heart problem make you feel hot?
Yes, inflammatory responses related to heart issues can raise body temperature, causing fever.
How does the heart regulate body temperature?
While not the controller, the heart helps maintain body temperature by circulating blood, distributing heat evenly (healthy.kaiserpermanente.org).
What is the relationship between body temperature and heart rate?
Heart rate increases linearly with temperature rise due to higher metabolic demands (Scand J Trauma Resusc Emerg Med. 2015).
