Is left ventricular end diastolic pressure 15 severe

Left ventricular end diastolic pressure of 15 mmHg is considered mildly elevated, and in most cases requires comprehensive evaluation based on clinical symptoms and other examinations. The main influencing factors include decreased diastolic function, hypertensive heart disease, coronary heart disease, myocardial hypertrophy, and excessive volume load.

1. Decreased diastolic function of the heart:

Decreased left ventricular diastolic function is a common cause, which is more common in middle-aged and elderly populations. The decreased active relaxation ability of the heart during diastole can lead to limited left ventricular filling, manifested as a mild increase in end diastolic pressure. Early improvement can be achieved by controlling blood pressure and limiting sodium intake. If accompanied by symptoms such as difficulty breathing, complete cardiac ultrasound examination is necessary. 2. Hypertensive heart disease: Long term uncontrolled hypertension can cause left ventricular myocardial remodeling, leading to thickening and increased stiffness of the ventricular wall. Patients with elevated end diastolic pressure are usually accompanied by morning dizziness and chest tightness after physical activity. It is necessary to evaluate blood pressure control through 24-hour dynamic blood pressure monitoring and use antihypertensive drugs in a standardized manner.

3. Coronary heart disease myocardial ischemia:

Abnormal energy metabolism of myocardial cells can affect ventricular diastolic function when coronary artery blood supply is insufficient. This type of patient may also have symptoms of angina pectoris, typically manifested as a feeling of compression behind the sternum after exertion. It is recommended to perform coronary CTA or exercise stress test to confirm the diagnosis, and if necessary, perform revascularization treatment.

4. Cardiac hypertrophy lesions:

Diseases such as hypertrophic cardiomyopathy or aortic valve stenosis can lead to abnormal thickening of ventricular muscles. Patients with ventricular septal thickness exceeding 15 millimeters can be seen on echocardiography, which may be accompanied by arrhythmia. Regular monitoring of dynamic electrocardiogram is necessary to avoid sudden death induced by intense exercise.

5. Excessive volume load:

Increased circulating blood volume caused by renal dysfunction or excessive infusion can significantly increase ventricular preload. Patients often experience lower limb edema and paroxysmal nocturnal dyspnea. Daily fluid intake should be limited, 24-hour urine output should be monitored, and diuretic treatment should be performed if necessary.

It is recommended to regularly monitor blood pressure and heart rate, and record weight changes on an empty stomach every morning. The diet follows the principle of low salt and low fat, with a daily intake of no more than 5 grams of sodium. Eat more foods rich in potassium ions such as bananas and spinach. Moderate aerobic exercise such as brisk walking and swimming, 3-5 times a week, for more than 30 minutes each time. If there is an inability to lie flat at night or worsening edema in both lower limbs, immediate medical attention should be sought to complete NT proBNP testing and cardiac ultrasound re examination.
