High cholesterol definition and self-testing guidelines: Analysis of seven symptoms and diagnostic criteria
Can you test your blood lipids yourself? High blood lipids are a risk factor for coronary heart disease, hypertension, and stroke. So, how can we know if we have high blood lipids and take timely and appropriate treatment? You can judge from the following aspects: Frequent dizziness or easily falling asleep while talking to others. Feeling mentally foggy upon waking in the morning, which improves after breakfast; feeling extremely sleepy in the afternoon, but very alert at night.
Xanthelasma palpebrarum is a sign of high blood lipids in middle-aged and elderly women. It mainly manifests as small, pale yellow rashes on the eyelids, initially the size of a grain of rice, slightly raised above the skin, and in severe cases, covering the entire eyelid.
Frequent leg cramps and tingling sensations are a sign of cholesterol accumulation in the leg muscles.
The appearance of numerous dark spots on the face and hands in a short period of time, slightly larger and darker than age spots. A significant decline in memory and reaction time.
Occasional blurred vision is caused by thickened blood and slowed blood flow, leading to temporary ischemia and hypoxia of the optic nerve or retina.
Hyperlipidemia and its Contributing Factors:
What is Hyperlipidemia: Hyperlipidemia is medically defined as a condition where abnormal lipid metabolism results in elevated levels of one or more lipids in the blood plasma. Lipids are insoluble or only slightly soluble in water and must bind to proteins to exist as lipoproteins in order to circulate in the blood. Therefore, "hyperlipidemia" is manifested through hyperlipoproteinemia. Total cholesterol and triglycerides are the main lipid components in blood plasma.
Although numerous medical studies have proven that hyperlipidemia is a major risk factor for cardiovascular and cerebrovascular diseases, there is still intense debate regarding the criteria for hyperlipidemia, especially those suitable for China. The U.S. National Cholesterol Education Program and the European Atherosclerosis Association have proposed the following criteria for hyperlipidemia: total triglycerides greater than or equal to 2.26 mmol/L, total cholesterol greater than or equal to 5.70 mmol/L, and high-density lipoprotein less than or equal to 1.03 mmol/L. A large-scale survey in my country showed that when total plasma cholesterol is greater than or equal to 4.66 mmol/L, the risk of cardiovascular and cerebrovascular diseases increases significantly, and this was used as the upper limit of normal blood lipids for Chinese people.
What is premature contraction? What are its dangers and clinical manifestations?
This article details the definition of premature contractions (also known as premature beats) and their classification as ventricular and atrial, explaining their interference with the normal filling and ejection of blood from the heart, and their potential long-term harm, which can lead to heart failure or even sudden death. It also lists common clinical manifestations such as a "thumping" sensation in the heart and chest tightness.

This article provides three practical self-assessment methods for premature contractions (PVCs) and details prevention and treatment strategies such as medication and diet. It also lists four typical symptoms of heart failure, such as exertional dyspnea and lower extremity edema, to help you identify abnormal cardiac signals early and respond scientifically.

A Breakthrough in Heart Failure Rehabilitation: Free Exercise Therapy Improves Cardiac Function
This article shares the recovery journey of a patient with severe heart failure following a myocardial infarction. The patient's ejection fraction was only 28%, but after 7 months of standardized medication combined with individualized aerobic exercise training, it increased to 58%, and symptoms were significantly relieved. This case demonstrates that consistent and appropriate exercise under the guidance of a doctor is an effective non-pharmacological means of improving cardiac function and enhancing quality of life.
