A mature Caucasian patient, an endurance-trained triathlete (age group), had a routine ECG. The patient was immediately referred to Emergency based on supposed ECG abnormalities indicating a heart attack. This diagnosis was quickly dismissed based on no symptoms, heart rate of 50 BPM, athletic status, excellent health, and no prior cardiovascular problems. The patient had a history of severe white coat hypertension and underwent a further stress test and echocardiogram. The stress test showed exaggerated systolic blood pressures (over 225 mmHg) and high in-clinic basal blood pressures (160/90 mmHg), and the patient was diagnosed as hypertensive with exercise blood pressure close to stroke territory. He was told to stop racing, reduce training, and was prescribed antihypertensive drugs (which he did not take). Subsequent at-home 24 h (values close to 120/80 mmHg) and stress blood pressure measurements reversed that decision when considered in combination with an excellent echocardiogram result. The literature clearly describes endurance-trained athletes with systolic pressures over 225 mmHg Hg as being conditioned with no pathological aspects. Endurance-trained athletes should be examined as special cases in the field of cardiovascular medicine as trained physiological responses often present as cardiac abnormalities, and misdiagnosis can inappropriately change the athlete’s life.

Heart failure (HF) is a syndrome suffered by more than 26 million people worldwide. SGLT2 inhibitors are drugs that have been shown to positively affect the management of HF patients, regardless of their diabetes status. A retrospective observational study was conducted on heart failure patients with reduced ejection fraction (HFrEF) enrolled at the HF clinic, who were on SGLT2 inhibitors. For these patients, baseline and follow-up data were collected and analyzed over time. Changes over time were quantified and statistical analysis was conducted to validate whether the changes were significant. After the screening of all the HF program patients, 24 met the inclusion criteria, with an average age of 68 years. Through the study, it was possible to find a statistically significant difference in the values of NT-ProBNP before and after adding a SGLT2 inhibitor in 14 patients (p = 0.0214). In addition, there was an improvement in the NYHA functional scale of 71% and no significant change in renal function or other laboratory values. Based on the studied parameters and throughout the clinical changes during the follow-up period, it was possible to establish an improvement in HFrEF patients on SGLT2 inhibitors as part of their therapy.

Deep vein arterialization (DVA) is a therapeutic option in “no option” for revascularization chronic limb-threatening ischemia patients, creating an arteriovenous bypass between a proximal artery and a distal deep venous target at the ankle. Imaging plays a crucial role in peripheral arterial disease (PAD) patient management. We present the case of a 71-year-old PAD patient (Rutherford class 5) with focal gangrene of the first and second toes of the right foot, who was admitted to the vascular surgery department to undergo revascularization surgery by femoro-tibial artery bypass. During surgery a DVA was performed because of an unsatisfactory distal artery target. The post-operative computed tomography angiography showed the saphenous graft patency and opacification of distal foot veins. Subsequent angiography documented the presence of a large venous collateral, responsible for extensive early wash-out to leg venous vessels, which was then embolized. After two months, the patient underwent amputation of the right first and second necrotic toes at the level of the metatarsophalangeal joints. The post-operative course was excellent, with disappearance of pain at rest and good trophism of the surgical wound. Full article

Overdose of amlodipine, a dihydropyridine calcium channel blocker (CCB), is distinguished from other CCBs due to longer plasma half-life of 30 to 58 h. As current management strategies of CCB overdose are diverse and institution dependent, this retrospective observational study aimed to compare treatment and outcomes data extracted from published case reports of amlodipine overdose with a cohort of patients diagnosed with amlodipine overdose at an urban tertiary medical center. Particular attention was paid to the use of high dose insulin euglycemic therapy (HIET) in treatment of amlodipine overdose. Data was extracted from actual adult patients hospitalized for amlodipine overdose at an urban tertiary medical center up to 2018, and from case reports of amlodipine overdose published between 1997 and 2020. We found a tendency towards earlier and more frequent initiation of HIET over time in management of amlodipine overdose, facilitating hospital discharge. Given the lack of randomized controlled trials comparing vasopressors, HIET, or other therapies, optimal treatment for amlodipine overdose has yet to be definitively established. Based on currently available evidence, a reasonable approach to management of the hemodynamically unstable patient presenting with amlodipine overdose includes vasopressors and inotropes with earlier initiation of HIET.
