In Chinese medicine, Heart can be diagnosed as "Heart Full" (always too tired), which leads to "Heart Large" (cardiac failure), "Heart Small" (results from prolonged birth delivery, or a sudden, profound shock; can lead to coronary artery disease), "Heart Tight" (worrying, racing mind, sleeplessness; leads to angina), and "Heart Closed" (energy has become very restricted or stagnant; person is always in some emotional difficulty, and likely to be vengeful or spiteful).
