[Read more] People naturally think of heart disease when they experience chest tightness, panic attacks, and severe pain in the precordial region. However, some heart diseases do not have obvious precordial symptoms. They will send signals with other symptoms. At this time, can you listen to them? 1. toothache Toothache is usually considered dental disease or periodontal disease. However, a few angina patients show toothache during the attack. Therefore, when toothache occurs suddenly, especially when it is accompanied by chest discomfort or profuse sweating, you must consider angina attack and seek medical attention promptly. 2. Swelling of the lower limbs Swelling of the lower limbs in the elderly is often a sign of cardiac insufficiency, resulting in obstruction of venous blood return. This is a typical symptom of heart disease. 3. Shoulder pain Shoulder pain in middle-aged and elderly people is mostly caused by frozen shoulder or cervical spondylosis. However, sometimes heart disease can also be manifested as shoulder pain, especially when the shoulder pain is not related to the climate and is manifested as paroxysmal soreness in the left shoulder or the inner side of the right arm. According to the survey, shoulder pain accounts for 65% of the total number of patients with coronary heart disease. 4.Long-term continuous snoring The British medical profession has conducted a 3-year follow-up survey on 4388 cases of men aged 40-60, and divided them into long-term continuous snorers, snorers and occasional snorers, and found that the number of long-term snorers suffering from heart disease is much higher than others. 5. Tinnitus Studies have found that heart disease patients have varying degrees of tinnitus in the early stages, because the microscopic blood vessels in the inner ear are more sensitive to blood changes. This is because the microscopic blood vessels in the inner ear are sensitive to changes in blood flow, and the inner ear gets an aura signal when the cardiovascular dynamics have not yet caused a systemic reaction. 6. Abdominal pain About 8% of patients with acute myocardial infarction present early with sudden onset of severe pain in the upper abdomen, accompanied by nausea and vomiting, with or without local pressure pain, which can be easily misdiagnosed as acute perforation of gastric and duodenal ulcers, acute cholecystitis, etc. Middle-aged and elderly patients with a previous history of coronary heart disease and angina pectoris should be alerted to acute heart attack if they have sudden severe epigastric pain.
