Adopting an extreme lifestyle combining nocturnal sleep patterns, massive overeating, and substance abuse strains the body to the point of causing a fatal cardiac event.

The idea that a lifestyle combining sleep disruption, extreme dietary excess, and substance abuse places significant strain on the heart is well-supported by science. Regarding sleep, a scientific statement from the American Heart Association (based on observational studies) confirms that disrupting our internal clock significantly increases risks to heart health. As for gargantuan meals, a study from Boston University presented to the AHA (an observational study) indicates that an exceptionally heavy meal can temporarily quadruple the risk of a heart attack, due to the intense digestive effort that diverts blood flow. The impact of substance abuse on heart exhaustion is also widely documented by cohort follow-up reports. However, labeling Elvis as a "food addict" or stating with certainty the exact sequence of causes for his death remains historical speculation without direct clinical evidence. Overall, while the narrative regarding the star's life is popularized, the risks of this cocktail of lifestyle habits on longevity are quite real.
