Introduction Sean is a 52-year-old man, who has an impressive history of hypertension. He stopped using his HTN medications three months ago. His current visit to the practice clinic is caused by the sudden chest pain accompanied with short of breath, nausea, and sweaty feeling. That condition lasted for about three minutes, then stopped, and never repeated. From that period, Sean feels tired from time to time. He did not work a lot after that event happened to him.

Differential Diagnoses   * Pneumothorax, unspecified (J93.9): is a sudden attack that is characterized by severe unilateral chest pain that has a pleuritic nature (Buttaro, Trybulski, Bailey, & Sandburg, 2013, p. 528). This condition includes the collection of extra air or some gas in the pleural space that causes the collapse of lungs. According to Bobbio et al. (2015), this condition has specific characteristics that conclude that older aged male people have more chances to have pneumothorax (p. 657). In this case study, the patient is a 52-year-old male, whose main complaint is the pain in his chest and the inability to breathe free for a couple of minutes. It was a single episode that looked like a heart attack, and pneumothorax could be a complication to expect in the patient with hypertension and heart problems.   * Atherosclerotic heart disease of native coronary artery without angina pectoris (I25.10): is the condition that is also known as coronary artery disease (CAD). This disease occurs when the damage to blood vessels that take responsibility for blood and oxygen transformation occurs. The main risk factors for this type of heart disease include hypertension, a high level of cholesterol, and smoking (Brown, 2014, p.52). In the situation under analysis, the patient has a rich hypertension history and a high level of cholesterol. He also smokes cigars while playing poker with his friends. Chest pain is the sign to check the condition of his heart in a short period of time.   * Anxiety disorder, unspecified (F41.9) : is the psychological disorder that is usually characterized by anxious feelings and fears, tension and dyspnea, irritability and phobias. The connection between anxiety and cardiovascular disease has been discussed and proved by a number of researchers (Allgulander, 2016,
