Yes, feeling hot, flushed, and sweating excessively can be a symptom of heart failure or a sign of a heart attack, especially if it comes with other signs like shortness of breath, dizziness, or chest pain, because the heart struggles to regulate body temperature and manage heat. Heat intolerance, profuse sweating, and clammy skin are common indicators that the cardiovascular system isn't working effectively, requiring medical attention for assessment.
EXCESSIVE perspiration has been noted for a number of years to be one of the signs and symptoms of congestive heart failure in this clinic. As a matter of fact, it is so frequent that our standard cardiac clinic sheet lists increased sweating as one of the symptoms to be checked on the first visit.
Profuse sweating is a symptom often reported by cardiological patients and could be also an early phenomenon of adaptation or rather cardiac maladaptation in the context of incipient heart failure (HF).
Exposure to high heat and humidity with congestive heart failure can cause you to overheat. You may develop symptoms such as excessive sweating, muscle cramps, rapid pulse, clammy skin, nausea, headache, dizziness, or weakness.
The following are heart attack warning signs:
Lightheadedness, fainting, sweating, or a sick stomach. Unexplained shortness of breath. Unexplained anxiety, weakness, nausea or tiredness.
Sweating, battling night sweats, or feeling overheated when combined with other symptoms on this list should be a major red flag.
Having hot flashes does not mean you're going to have a heart attack. Instead, it indicates that some of your arteries may not be working as well as they should. Knowing that can help you and your health care provider better assess your overall risk for heart disease and other cardiovascular problems.
Heart failure symptoms may include: Shortness of breath with activity or when lying down. Fatigue and weakness. Swelling in the legs, ankles and feet.
When your heart failure is not very bad, your health care provider may not place you on a fluid restriction. As your heart failure becomes worse, your health care provider may limit your fluids to 6-9 cups (1.5-2 liters) a day. Having other conditions like kidney disease may factor into their decision, too.
In most cases, the cause isn't known. This is known as primary hyperhidrosis. But it may be caused by thyroid problems, low blood sugar, nervous system disorders, medicines, or other problems. This is known as secondary hyperhidrosis.
People with congestive heart failure (CHF) often have a hard time falling asleep or staying asleep. This is due to the shortness of breath that is caused by CHF. This shortness of breath is often made worse when you lie down. The blood in your legs flows back into the heart.
A number of conditions can cause hot flashes and palpitations including acute stress or panic attack, supraventricular tachycardia, or atrial fibrillation.
The changes in the cardiovascular system that develop in chronic heart failure obviously affect thermoregulation. A constant, normal body temperature is the consequence of a regulated balance between heat production and heat loss. Both sides of this balance are altered in chronic heart failure.
End-stage heart failure symptoms
It's normal to sweat when you're hot or when you're doing physical activity. However, if you're sweating a lot when your body doesn't need to cool down, this is excessive sweating. Often there's no obvious cause for excessive sweating. This is known as primary hyperhidrosis.

8 Conditions That Can Be Mistaken for a Heart Attack or Heart Failure
The symptoms of heart failure may be subtle and are often mistaken for normal signs of aging. Common symptoms of heart failure are due to extra fluid or congestion. Typically starting with congestion of the lungs, then congestion of different parts of the body. At advance stages, the cardiac output decreases.
Summer heat and heart failure
Heart failure is a condition where your heart doesn't pump effectively and therefore can't move blood through your body as quickly as it should (cardiac output). Reduced cardiac output makes it more challenging for your body to cool you down.
In the Study of Women's Health Across the Nation (SWAN) Heart Study, women reporting hot flashes had greater evidence of subclinical cardiovascular disease (CVD) compared to women not reporting hot flashes.
Conditions that can cause hot flashes besides menopause include certain medications, being overweight/obese, food allergies or sensitivities, niacin supplements, anxiety, rosacea, hormone conditions, endocrine imbalances such as overactive thyroid, carcinoid syndrome, infection, cancer, and hot sleeping conditions (“ ...
What are the symptoms of heart failure?
The most common symptoms to track: Shortness of breath or extra fatigue while moving through your daily routine. Two signs that congestion is getting worse are: Difficulty breathing when lying flat.
It can severely limit the activities you're able to do and is often eventually fatal. But it's very difficult to tell how the condition will progress on an individual basis. It's very unpredictable. Lots of people remain stable for many years, while in some cases it may get worse quickly.
