What are the early symptoms of heart disease affected by kidney deficiency?

Under normal circumstances, the early symptoms of heart disease influenced by kidney deficiency are relatively subtle and may include palpitations, chest tightness, shortness of breath, reduced physical stamina, dizziness, fatigue, and frequent awakening at night. A detailed analysis is as follows:

1. Palpitations: According to Traditional Chinese Medicine (TCM), the kidney is the root of the heart. Kidney deficiency can lead to insufficient heart qi and inadequate nourishment of cardiac activity. In the early stage, this often manifests as palpitations without obvious triggers, more likely to occur during rest or after physical exertion, with sensations of irregular heartbeat or excessively strong pulsations.

2. Chest tightness and shortness of breath: Kidney deficiency impairs the circulation of qi and blood, resulting in insufficient blood and oxygen supply to the myocardium. Mild chest tightness may appear early, worsening with emotional fluctuations or physical activity, accompanied by shortness of breath that requires deep breathing for relief; symptoms gradually subside after rest.

3. Reduced exercise capacity: Compared to previous levels, individuals may notice a significant decline in endurance. Activities or household tasks that were once easily completed may now be interrupted due to discomfort such as palpitations and shortness of breath—this is a typical early sign of impaired cardiac function.

4. Dizziness and fatigue: Kidney deficiency leads to inadequate production of qi and blood, weakening the heart's pumping ability and causing insufficient cerebral perfusion. Early symptoms often include dizziness and a feeling of head fullness, particularly noticeable during postural changes, along with generalized weakness, low energy, and difficulty concentrating.

5. Frequent nighttime awakening: Kidney deficiency can impair nourishment of the mind (shen), compounded by relatively insufficient myocardial blood supply at night. This may lead to light sleep and easy arousal during the night. Some individuals may also experience mild chest tightness at night, requiring several minutes upon waking before symptoms ease.

These early symptoms are easily overlooked. It is important to address them promptly based on the individual's kidney-deficient constitution. Through tonifying the kidneys, nourishing the heart, replenishing qi, and promoting blood circulation, further deterioration of cardiac function can be delayed and overall bodily functions maintained in a stable condition.
