A heat transfer plate (8) and a plate heat exchanger (2) comprising such a heat transfer plate is provided. The heat transfer plate has a central extension plane (c-c) and comprises a first end area (28), a heat transfer area (32) and a second end area (30) arranged in succession along a longitudinal center axis (y) of the heat transfer plate. The longitudinal center axis divides the heat transfer plate into a first and a second half (20, 22). The first end area comprises an inlet port hole (34) arranged within the first half of the heat transfer plate, a distribution area (42) and a transition area (44). The transition area adjoins the distribution area along a first borderline (46) and the heat transfer area along a second borderline (48). The distribution area has a distribution pattern of distribution projections (64) and distribution depressions (66) in relation to the central extension plane, the transition area has a transition pattern of transition projections (84) and transition depressions (86) in r
