A feeling of pressure on the heart while sleeping at night is considered a possible case of resting angina pectoris. In addition to this, it is considered possible that the patient may have heart failure itself, and may also have symptoms of chest tightness, shortness of breath, wheezing, and discomfort in the precordial area. Especially when the patient sleeps at night with a feeling of pressure, sitting up and feeling less pressure on his own is highly considered to be due to heart failure. If you want to further clarify the diagnosis, it is recommended that the patient can have a BNP, cardiac ultrasound, electrocardiogram, and chest X-ray for preliminary screening. A chest X-ray can help to clarify the patient’s heart, whether there are any structural changes in the heart, such as whether there are changes in size, and whether there is calcification of the aortic node, which can predict the degree of atherosclerosis in the patient at present. In addition, the most important thing is also to see the absence of pulmonary infection, because many patients with heart failure or exacerbation of heart failure are caused by respiratory infections.
