What are the dangers of heart disease
Heart disease is one of the leading causes of death worldwide. Its harm is not limited to the heart itself, but also has serious effects on multiple systems throughout the body. The following is a summary of the dangers of heart disease in hot topics on the Internet in the past 10 days, combined with structured data to provide you with a detailed analysis.
1. Classification and harm of heart disease
| type | Main hazards | high risk groups |
|---|---|---|
| coronary heart disease | Myocardial ischemia, angina pectoris, myocardial infarction | Middle-aged and elderly people, smokers, patients with high blood pressure |
| Arrhythmia | Sudden death, heart failure, stroke | People with electrolyte disorders, cardiac surgery patients |
| heart failure | Multiple organ failure and severely reduced quality of life | Long-term heart disease patients and diabetics |
| congenital heart disease | Developmental delays, recurrent infections, heart failure | Newborns, children |
2. The harm of heart disease to the whole body system
1.cardiovascular system: Heart disease directly leads to a decrease in the pumping function of the heart, causing insufficient blood supply to the whole body. In severe cases, cardiogenic shock may occur, with mortality rates as high as 50% or more.
2.nervous system: Arrhythmia can easily lead to cerebral embolism. Data shows:
| Heart disease type | stroke risk |
|---|---|
| atrial fibrillation | increase 5 times |
| endocarditis | Increase 20-40% |
3.respiratory system: About 90% of patients with heart failure will have dyspnea, and paroxysmal dyspnea at night is a typical manifestation.
4.renal system: Cardiorenal syndrome worsens kidney function, and data shows that patients with heart disease:
| Kidney function indicators | Abnormal ratio |
|---|---|
| Elevated serum creatinine | 35-50% |
| Decreased eGFR | 60-70% |
3. Economic and social burden of heart disease
According to the latest statistics:
| project | data |
|---|---|
| Global annual death toll | About 17.9 million |
| Number of patients in China | Over 330 million |
| Average annual medical expenses | Personal burden is 20,000-50,000 yuan |
| Incidence rate among working population | rose to 26.8% |
4. Suggestions for preventing heart disease
1.Regular physical examination: People over 40 years old should undergo electrocardiogram, blood pressure, and blood lipid examinations every year.
2.lifestyle:
| improvement project | Effect |
|---|---|
| quit smoking | Risk reduced by 50% in 1 year |
| Exercise 150 minutes a week | Risk reduced by 35% |
| mediterranean diet | Risk reduced by 30% |
3.drug control: Patients with high blood pressure and diabetes must strictly follow the doctor’s instructions when taking medication.
5. Latest research trends
1. The gene editing technology CRISPR has made a breakthrough in the treatment of hereditary heart disease, and the success rate of animal experiments has reached 75%.
2. The accuracy of the artificial intelligence ECG analysis system has been increased to 98%, and it can warn of cardiac events 72 hours in advance.
3. The new anticoagulant drug reduces the risk of bleeding by 40% and is undergoing phase III clinical trials in China.
The harm of heart disease cannot be ignored, but through scientific prevention and standardized treatment, most adverse consequences can be effectively avoided. It is recommended that the public improve their health awareness and conduct regular heart health assessments to achieve early detection, early diagnosis and early treatment.
