<unk>  classically produces chest pain at rest, also known as vasospastic angina. Chest pain is more common at certain times of the day, usually from late night to early morning. These episodes can be accompanied by nausea, vomiting, cold sweating, and even syncope.<unk>  is also associated with symptoms of fatigue and tiredness, dyspnea, and palpitations. These can sometimes be the primary presenting symptoms, but they can also occur in conjunction with chest pain. There are cases of<unk>  that occur without any symptoms at all, leading to episodes of silent or asymptomatic myocardial ischemia. Complications Depending on how long the occlusion lasts, a spectrum of different myocardial ischemic syndromes can occur. Shorter episodes of occlusion can lead to what is referred to as silent myocardial ischemia due to its asymptomatic nature. These episodes can also be accompanied by arrhythmias. Longer episodes of occlusion can lead to stable or unstable angina, myocardial infarction, and sudden cardiac death.
